Mesa/Boogie Mark IIB – 100 Watt, Early 80s – Serviced – Player’s Dream Tone Machine

Classic Boogie Sustain. Organic Celestion Tone. Fully Serviced & Ready to Play.

If you know Mesa history, the Mark IIB is where the magic really starts—tight low end, rich cleans, and that legendary singing lead tone.

This is a great early-’80s example (Serial #5833) that’s been professionally serviced and is ready to plug in and play immediately.

Tone & Feel (Why Players Love These)

This amp is all about usable, musical tone:

• Warm, full-bodied cleans with headroom
• Smooth, singing lead tones (classic Boogie sustain)
• Natural breakup that feels responsive—not stiff
• More forgiving and organic than later high-gain Marks

Loaded with an original-era Celestion-style speaker, giving it:

• Classic rock / blues-friendlyresponse
• Earlier, more musical breakup vs. EV speakers
• Lighter weight and easier portability

Features

• 100/60 watt switchable power
• Lead channel with cascading gain
• Reverb
• Effects loop (send/return)
• Slave out
• Made in USA
