I'm putting together a pedal board with the primary purpose of giving myself added tonal control in situations where I either don't generally use an amp (certain coffee house gigs) or have to use someone else's rig. The control center of this pedalboard is a Radial Tonebone Bassbone. I just got this pedal, it seems like a great unit and I can't wait to take it out and use it in a live situation. The Bassbone has a switchable effects loop, and I'm thinking what I could really use is some sort of tube pedal, maybe the Blue Tube 903, to kick in for solos when I'm playing my Modulus 6 string and to add some natural compression and some grit to my fretless or electric upright. I'm not interested in getting distortion/overdrive as much as just some grit and compression. So, is the Blue Tube pedal what I'm looking for, or is there something else that might fit the bill a bit better? I really want a pedal for this purpose...I need something very small and portable.
