There are a lot of versions of the IIC family and not all will agree on which is best. I hear that Metallica used a IIC+ Simul Class and usually just used its preamp section into other amps. The most sought after of all the Mark Series Boogies, if not all Boogies is the IIC+, Simul Class with all the options, with a hard wood cab being a plus for some (mostly collectors). These have now cracked the $4K barrier. In addition to the options already listed, people will argue which is the best sounding transformer for their needs.
Some say (including Mike Bendinelli of Mesa Boogie) that the X100 transformer has the sweetest sound. Some say that the X105 transformer has the most punch and headroom for rock. The export transformer is said to be the best match for Class A operation. Some like the EVM best and others like the Celestion.
Some have installed the Altec 417-8H from earlier Mark amps in and prefer it. They are all very nice to play through and the way the sustain decays makes you want to hold onto notes longer and makes you play differently.
I don't ever seem to be able to play through mine without playing a few Santana passages.
Hey Zach: I’ve got an early 1980s Boogie Mark amp and I’m trying to figure out exactly what model it is. It has the 5-band graphic EQ and the Simul-Class switch, so I think it is a Mark IIB. The clean channel has a really shimmering tone and breaks up a bit when pushed.

Can you verify this and possibly estimate its current value? —Allen in Detroit, Michigan Hey Allen, Mesa/Boogie is a true American success story. They’re one of the few long-time amp companies out there still building amps in the US under original ownership, and the company is continuing to evolve with new technology and ideas.
Founder Randall Smith spent a lot of time around electronics as a child. While he was in a band during the mid 1960s, he had the opportunity to fix a blown amp. After he successfully repaired that amp, Smith and his band decided to open a music repair shop that became the humble beginnings for Mesa/Boogie.
At the time, Barry Melton was the lead guitarist for Country Joe & the Fish, and when Melton’s roadies asked Smith to modify a 12-watt, 1x10 Fender Princeton, he turned it into something like a 60-watt Fender Bassman driving a JBL D-120 12' speaker. Smith soon became known for his ability to hot-rod small combo amps and, in his words, “What started out as a joke became the foundation of the company.” Smith’s shop was a popular place among the hippie musicians of the era, and one day Carlos Santana wandered into the store and played one of Smith’s modified Princetons. Santana loved the amp and is quoted as saying, “This little amp really boogies.” This comment ultimately led to the company’s “Boogie” moniker. Smith estimates he built around 200 of these modified Princetons before Fender figured out what he was up to and cut off his supply! In 1970, Smith left the music shop and ventured out on his own.
In order to obtain parts and supplies at wholesale prices, he started MESA Engineering. In the early 1970s, Smith began experimenting with new preamp designs to produce the type of gain and distortion guitarists were requesting. The result was what is now known as cascading gain, and it was incorporated into the very first Boogie production amp line—commonly referred to as the Mark I. As Mesa/Boogie evolved during the 1970s and early 1980s, they made several changes to their little combo amps. To indicate the change in each new variation, Mesa began calling their amps the Mark I, Mark II, Mark IIB, Mark IIC, etc.
The original Boogie had two channels, but there was no provision for switching between them without changing input jacks. After building approximately 3000 of the Mark I models, Mesa introduced the Mark II in 1978. It had footswitchable channels and an optional 5-band graphic EQ. In 1980, Mesa introduced the Mark IIB, which had an effects loop, an expanded control panel that included Lead Drive and Lead Master controls, and their famous optional Simul-Class system. The Mark IIC and IIC+ debuted in 1983, and they featured a quieter footswitch and a revised reverb circuit. The Mark IIC+ also had a revised lead channel and an effects loop.
The Mark II series lasted through 1985, when it was replaced by the 3-channel Mark III series, which was produced through 1999. Mesa/Boogie introduced the Mark IV in 1990, and it’s one of those amps that has everything except the kitchen sink. For Mesa’s 40th Anniversary, the innovative company introduced the Mark V, an amp that incorporates features from the Mark I, Mark IIC+, and Mark IV. Based on the features of your amp—including the Lead Drive and Lead Master controls, and the 100- /60-watt power switch—I believe you’re correct that it is a Mark IIB (but without Simul-Class).
That means it was produced between 1980 and 1983. Mesa has extremely detailed records, so you can contact the company and provide them with the serial number to figure out exactly when your amp was built. There are several misconceptions about the exact meaning of Mesa’s model designations, such as the “+” portion of the Mark IIC+. It is very important to note that each model designation indicated an overall design change and not a specific feature or option (such as EQ or reverb). Mesa often built amps to customers’ requests, so it is very common to find each model variation with different features. It is also quite common to find these Boogie amplifiers heavily modified from their original configuration.

Powtoon free trial. As you’ve probably heard from many Mesa/Boogie users, each Mark model has a different sound, and these differences affect the overall value. The Mark I is popular because it is the original Boogie. Many players love the clean channel on the Mark II and Mark IIB because of how it breaks up slightly when turned up. The Mark IIC/C+ is probably the most collectible Boogie, because the circuitry had been refined to what many consider optimal settings, yet it’s still simple to operate. The Mark III is less popular because the new channel design didn’t work the way many users had hoped. The Mark IV and Mark V are still so new that not much of a collectible market has been established yet.

Another thing to keep in mind is that, Boogies with wood cabinets (like yours) are much more valuable than those with vinyl coverings. Your amp appears to be in excellent overall condition and is currently valued between $1300 and $1600 in the vintage amp market. This Mesa/ Boogie is a great example of the American dream amplified, and it should be a reliable treasure for years to come.

Mesa Boogie Dual Rectifier Serial Number Lookup
Post 1985 Guitar Amp heads and combos As of the late ‘80s, Mesa began the use of a.75 inch x 1.5 inch decal that is often placed near the AC cord or IEC cable receptacle as shown in the picture above of this Dual Rectifier chassis. Serial Number decal on a Dual Rectifier head For those new to some of the terminology, the chassis is metal and houses of all the knobs, switches, transformers, tubes and sockets etc. the 'guts' of the amp. The serial number of your amp is always going to be attached to this part of your amplifier. The cabinet is the wood enclosure in which the chassis gets mounted. The cabinet is most often covered in vinyl with the exception of cabinets that are custom and covered in leather or custom hardwood cabs, or, rack mounted amplifiers. Walkabout rackmount unit with serial number decal on the underside of the amp towards the rear Some bass amps with serial number decals on the bottom of the amp AND built into head cabs will have to be disassembled from their head cabs to access the serial number.
Assembly instructions for bass amp head cabs can be obtained from Mesa/Boogie Customer Service. The serial number is also printed on the quality control card (if available) which may allow you to avoid disassembly. In the case of the Titan below, the serial number is on the rear panel and is easily seen even when in the head cab. Mark IIB amplifier with tech initials and assembly date on the underside of the amplifier between preamp and power tubes Some people like to know the 'birthday' of their amps and many will be pleased to find Mesa techs initialing and dating the amps in plain view very near the serial number decal on the amps since 2008-2009. For amps built before then, birthdate information may be available on the outside of the chassis near preamp tubes (as shown above) or, inside the chassis which requires disassembly to see the inside) but these dates are not always availablew on every model. If, after reading this material you can’t find your serial number, see the Serial Number By Location table below for more specific detail per amp.
If you still can't find the serial number, consider the possibility that a previous owner (or thief) may have removed the serial number decal or obscured a stamped number. Feel free to call Mesa Customer Service at 707 778 6565 Monday-Thursday, 9AM-5PM Pacific time for further assistance if this hasn’t taken you right to the serial number information you've been searching for all this time!
