PreTeen Bass PreAmp

ABOUT
After building the BeefyTeen head amp where one feature that it had as well as the original B-15’s was an External amp jack. A friend ask me if I could build the pre amp section so it wouldn’t be necessary to drag around an extra speaker thus the PreTeen was born. The PreTeen is the tone circuit from the second channel of iconic Ampeg B-15NB and B-15NC Portoflex which have the tone stack before the volume control. Just like on the Ampeg B-15 and BeefyTeen, PreTeen uses a 6SL7-GT octal preamp tube and a 5AR4 rectifier tube. The PreTeen can be used with much more powerful amp such as a MarkBass SS amp or plug into a DI with Balanced XLR in the studio either way you get the warm sound of “The 60’s Bass” tube amp.
