About a month or so ago, I took a one of my amps to amp repair guru Skip Simmons. Skip is well known for his refurbishing of old amplifiers and old PA heads. When I picked up my amp, he talked briefly. He handed me a box, asked me to take it home for a while, try out what is inside and let him know what I thought.
What was inside the box?
A Masco MA-17 PA head that has been refurbished to the original 1944 specifications. Skip had built up a few of them for Paul Oscher. He sent him a couple of modified heads and a stock one. The stock one was returned.
I took it to the jam at the Mojo Lounge and played through it. I plugged it into a 15" speaker that was in East Bay Wes's 1963 Vibroverb amp. It's amazing how loud 18 watts can be. It had a bottom end as fine as Jennifer Lopez. It sounded great.
A few weeks ago, I had a few spare hours in the evening. I plugged it into the pair of Weber 8" speakers in my Harpgear Double Trouble. I pulled out an old vintage JT-30 and started messing around. I cranked it up to the brink of feedback and cranked up the tone control. The sound was huge and vintage postwar 1950's Chicago Blues. I shot a little bit of video, but the camera could not capture the huge bottom that was pouring out of the Double Trouble's speakers.
A couple of days later, I decided to try the Masco with a pretty common microphone, a dynamic Shure 520DX aka the Green Bullet. I sounded pretty similar to the vintage Astatic microphone.
This amp is a definitely keeper, but I decided to postpone the purchase until the economic climate becomes a bit better. I do see one of these in my future when things stabilize.
