CPC-45M Heads
Post Phase Inverter Master Volume Option

The JTM-45/Bluesbreaker is one the most talked about and loved vintage amps. Clapton’s untouchable playing with the Bluesbreakers, Angus and Malcom Young grinding out AC/DC’s early records, Gary Moore, Joe Perry on recent tours and countless others prove why this amp really is the cream of the crop.  It’s bluesy and gusty with loads of punch and cut.  It’s basically Jim Marshall slightly modified Tweed Bassman. The JTM45 was the touchstone for every good Marshall amp that followed.

I offer the amp in 45W or 20W. Both use KT66 power tubes so the tone is very very similar.

My JTM45 is captures both the sound and power of the JTM45 but has lower floor noise. Mine is easily better than the corner cutting reissues and kit built JTM clones.

Customer Comments:

"I bought Carl's 20watt JTM45 amp. The amp is simply AMAZING. With my Strat I can channel Jimi and with my Les Paul this amp nails the classic rock tone. But most importantly, this amp responds to my volume knob very well. I roll back the volume and get a warm, sparkly almost Fender-esque clean. I am fortunate enough to own some great vintage amps and this JTM will become my primary go-to amp. Carl was great to work with, he's incredibly knowledgeable and has a good sense of tone. I'd highly recommend Carl's Custom Amps and this JTM45."
