GENERAL “BIG M” INFO: The Ampeg Big M combo was manufactured from 1959-1963. It was the flagship amp for Ampeg and considered one of the best amps from that vintage era. Two 6L6 power tubes into a 15" Jensen C15N Alnico 5 and two fully separate channels with independent tone controls and up to 6 inputs on the front panel, including one for stereo! The Big M was known to have a great clear tone with clean overhead when cranked. It also had a great foot controlled Tremolo and plenty of output power.

THIS BIG M: Physically, this vintage original Big M is in great condition! You will not find a nicer original amp for being 60+ years old. Nothing is missing or broken and everything works like it is supposed to. The plywood cabinet, tolex, grill cloth, hardware, and speaker are all original, very clean, and in great working shape. Check out the pictures closely.

THE DETAILS: The electronics are the best part. In August, I had the amp completely gone through by Mike LaBar Electronics. The values of each component were individually measured and replaced where needed. Everything is up to factory spec. The only changes made were replacing the 2 prong power cord with a modern 3 prong and the original Tremolo footpedal was given a new cloth braided cord. New power tubes were installed as described below.

TUBES & POWER OUTPUT: The Big M uses two 6L6 power tubes cathode biased. There is no need to re-bias when changing power tubes. Multiple pairs of power tubes were sonically tried and measured. A new pair of Shuguang 6L6GC sounded best with clean headroom, balance, and a strong bottom-end. Power output measured 27.8 watts RMS, enough to kick ass! If you want, with this sale I’ll include the former power tubes, a pair of 1970's RCA 6L6's.

The three preamps tubes are 6SL7. Two of the three are the ORIGINAL factory tubes that came with the amp! They sound great without any microphonics. This model tube remains readily available for purchase.

SPEAKER: 15" Jensen C15N Alnico 5, the original USA made speaker. It works surprisingly well, sounds great, and is fairly lightweight.

TONE & PLAYABILITY: This sound of this amp blew my mind! It had not been used for over 10 years and I didn’t think the 1958 design would sound very good. I was wrong! The overall tone and performance is amazing! Its plenty loud. The tone is clear, balanced, warm, and very pleasing. The amp has plenty control over EQ, especially when linking the two channels with a jumper patch like the original Marshalls. The Tremolo is sweet and there is lots of clean headroom when cranked. Overall, it is a perfect pedal platform. In short, this BIG M has tone! Ya gotta hear it!

I will include with the sale a printed copy of the User’s Manual and a schematic. This is a very useful quality vintage amp that works great on stage, in the studio, or at home. It is priced to sell. Come check it out!
