    Hi there,

    I'm looking around at amps and am considering the Bass Terror. I love the tone with the gain cranked, but how would you switch between that and clean?

    I suspect the answer is reduce instrument volume (perhaps with a volume pedal or something?). Would this mean a pretty high noise floor and "dirty" clean tone? hmm...

    Also I have an old Jansen (New Zealand) bassman amp with possibly a burnt out output transformer. The power tube sockets are wobbly and the whole thing is in rather bad shape. Was thinking of pulling out the preamp section to make a standalone bassman preamp. Maybe a rack sort of deal. harvest organs/rebuild/dump?

    You don't switch. You have to move the knobs. This is why I greatly prefer pedals for live work.

    Thanks guys.

    Is boosting the signal (with a clean boost or something) into the preamp the same as turning up the gain on the preamp? Why not?

    I use the pedal live to give me the effect of another channel on the amp.
    You can get multi channel sansamps and store 3 sounds on pedal plus the amp itself giving 4 in total but I get by with just 2 and a tweek with the volume and tones on bass.

    Yup. Gain up, Volume lower down, for overdriven tones. Gain lower down, Volume up, for clean tones.

    Have you had a tech's opinion on it yet?
    They're simple and robust amps and quite rebuildable.

    Where in NZ are you?
    Matt(?) at Orchard amplification in Wellington is good with Jansens and knows a man in Foxton who can rewind Jansen transformers. Ryan from The Amp Shop in Auckland sure knows a thing or two about Bassmans too. He can supply JJ 7027A's at very reasonable cost and he has successfully converted a few 1970's Bass 75 amps to run 6550's in the output stage.

    I'm in New Plymouth and our tech here is Tony Baxter.

    I've got a late 1960's 75 Bassman which I really like.
