This is a pre-Fender SWR SM400s. I have done the very simple AE bypass mod which evens out the EQ curve significantly. The Aural Enhancer knob now functions as a 2nd gain knob to let you easily overdrive the preamp tube. I replaced the tired old GT 12 AX7 with a new JJ tube. This amp has come alive!!!
SWR Aural Enhancer Bypass
I'm only selling because I need to pay off some other gear purchases.
The price is $285 plus shipping.
Thanks for looking.
