I've had a K&K Bass Max for 10+ years and am perfectly happy with it. However, it appears the preamp has died on me. I am investigating a repair, but given my preamp needs (volume, input, output), it might be cheaper to just get a new preamp. My question is whether I should just get the K&K Pure Sound preamp or if there are other ones out there that might sound as good or better and/or suit my needs. I don't want to spend a ton of money. The Schatten Design Mini Pre caught my eye - has anyone used this or any other small (needs to mount on tailpiece) preamp with the bass max? L.R. Baggs also makes at least one (LR Baggs Gigpro Single-Channel Belt-pack Preamp). Thanks!
