I'm currently in the process of building a 5 string piccolo bass (BEADG, octave up) and I was planning on using the Glockenklang 3 band pre, which I have in my possetion already. However, as it stands at the moment, the body is SLIGHTLY too thin for the glock to fit. I can mod the bass to fit the preamp, but it would drastically change the look of the instrument, which is not necessarily a bad thing. I then considered using a Delano pre, as they are much smaller and supposedly just as transparent. However, the Glock has a treble frequency of 18KHz, which I figured would be ideal on a piccolo bass (the Delano has a centre of 6.5KH). Do any piccolo players have any advice on the matter? Or any EQ experts? Any help would be appreciated.
