NEED a BRAIN for your BLONDE?
If you want the missing link between your filtertron'd Hollowbody and vintage bassman amp, namely the RE-301 space echo, to get that blonde ol' stray cat sound.. I built this Pre-amp to have that particular catalyst and the mojo of what a 301's input circuit does to the gretsch guitar and blonde fender..
(I have redesigned the circuit to also work great with strats, teles, LP's and even Dynasonic and p-90 loaded guitars)
This is indeed a pre-amp, not an "FX" box, its not a boost or drive box. It causes the guitar to be heard better by the normal channel of a blonde 63' bassman..(the Dyno Brain and Atomic brain also work well with a wide variety of tube amps) I've spent yrs trying to make this happen, I'm no engineer, just a singer-guitarist with one sound in my ears I had to have... so I'm making em' 1 at a time!
