In fact, this thread has me thinking of hunting for another one!

You have to be able to get over the idea that you're looking at a cheap SF Fender Bass amp and ignore all the normal predisposition that goes with it and JUST use your ears. I was told they thought it was worth a shot as the amps weren't expensive (I think they ended up fetching $200 or so on eBay 5 or 6 years ago) but didn't expect much, and were shocked. I sold the last two I had because I have a 5D3 and needed room and money - both buyers were floored. There were quite a few (and still some) who scoff at it - and most of the naysayers are going on an empty tank as they've never HAD one or have but never stuck a decent alnico 12 in it *and* played with tubes (the lower-gain preamp tube is a big piece of the puzzle many buyers of Musicmasters miss). What you end up with is darned close to a 5D3 later wide-panel Deluxe sound. There are websites that list a few tweaks you can do - but honestly out of the 4 or 5 I've had (both the 6V6 and 6AQ7 - note they are NOT 6BQ7's aka EL84's and lots of p[layers by them making that mistake thinking they're getting a Vox clone.6AQ7's are very Fendery-sounding, plentiful and inexpensive) all I needed to do to get an absolutely stunning guitar tone was a simple cap job (needed anyway), a speaker replacement (MANDATORY - the speaker is junk almost anything is an improvement, but a P12Q-type is the secret weapon) and a lower-gain preamp tube (pick your poison - 5751, 12AY7 or even a 12AU7). It's mostly "weird" because it was so unlike Fender to use a more *expensive* system and parts, especially in the CBS days.

The transformer-coupled inverter is actually a much better system than a driver tube, which wears out, needs to be precisely balanced and can have a huge effect on tone and gain (in a bad way, mostly). "I read Gerald Weber's first book and I'm no a tech") think there is something "wrong" with them. The transformer-coupled phase inverter invariably makes people with a smattering of technical knowledge (i.e. They are probably one of the great "sleeper" amps of all time for small club and studio use - for guitar. We had several discussions where about these 7 or 8 years ago.
