Simple Tube Bass Pre-amp

[baggman]

Who has the simplest tube pre-amp plans for a bass amp. I want to build a hybrid bass amp for small gigs and recording. I guess something like an old Bassman, or Ampeg B-15 would do the trick. Thanks-baggman

Dr tube, lots of schems for guitar and bass tube preamps

Hope this helps baggman! Good luck with the build

Try a JTM45/early JCM800 split channel preamp - if you'll compare the schematics in Dr Tube's Marshall section, it'll be obvious what you need to change for bass use. Keep in mind that those amps are just ever-so-slightly modified Tweed Bassmans, so you can't go far wrong. The B15 is great, too, but doesn't grind quite as hard. Both pretty simple to build, so pick yer poison.

Thanks, lovekraft! That's a great idea! And would be perfect! -baggman
