1970s Acoustic Control 150 & 150b Amplifier Heads

Vintage solid state amps, made in So. Cal

Recently, I've made it known that Takamine is the favorite among acoustic guitars and Ibanez the preference of electric guitars. With that in mind, Acoustic Control is the brand of choice when it comes to amplifiers. The first pro rig that I ever had is an ACC 450 plugged into a Randall RB215 and that plays a large role in the interest.

Years later, I would score the ACC 230/403 half-stack that was featured in post #2 here at SCGM and the beast was unleashed. The guitar head was found at a great price just a few months after the 230 and also featured with a Sunn 412L cabinet that was picked up just down the road. One of the previous owners modified this head by adding a pot where one of the input jacks used to be and I think it was a way of controlling the level of the reverb and tremolo effects without a footswitch.

The bass head was found earlier this year by a local seller and is in great shape. The power cord has a couple of rough spots, but it still in working order. These are essentially the same amps, but the guitar version has the effects. The other cool thing is that I was finally able to find a footswitch for a decent price. These things can sometimes cost close to $100 on their own and that is just outrageous.

Thanks for looking, more high-resolution photos here.
