Picked up my second Arredondo Marshall a few weeks ago. This one is a 74’ Super Bass. Very similar to the 71’ Super Lead that I already have. Same mods. Except the Super Bass doesn’t have a loop. I absolutely love these old Jose’s.

What’s interesting about this amp is that everywhere Marshall would typically put a 100k resistor, it has 150k instead. I took it over to Dave Friedman’s. He said it was common to see that occasionally. If they ran out of 100’s they just used 150’s. So the plates, v2b cathode, NFB etc.. is all 150k. This amp sounds gainier and more bottom end than my 71’. They definitely both have their own character.

Both of my Jose’s have the push pull gain pot for extra stage on the back. Some of them have it in front in one of the input jack holes. Presence is changed to the MV and presence is on back. No diodes in either of my amps. I know of 4 other Jose’s in LA and none of them have diodes either.

Here’s some photos of the 74’ and also with the 71’ on top. Clip also attached. Straight into amp zero fx. SM57 and g12h30 anniversary.

Congrats! Killer amp! Crazy to think how far Marshall mods have gotten since Jose started up in the 70’s.
 
That is such a great sounding, straight up rock n roll amp. Can you imagine having that amp when all your friends had stock Marshalls…

Great clip too man- showcased that nicely
Thanks man.

Yeah imagine this thing back in 1983. That’s a long damn time ago! It was pretty much Jose and Lee Jackson. Not too many options in that day.

What’s funny is that these mods are essentially turning a 1959 circuit into a 2203 with the added stage, simulating the cascaded circuit. But no cold clipper and the extra stage cathode is bypassed with a cap. So more gain and aggression than a stock 2203. Obviously, there are other differences in a 2203 but the idea is similar.
