Radial Tonebone Bassbone preamp This is the original version of the Bassbone in good condition. Has some scratches and sign of use but nothing major. Velcro at the back had been cleaned up. Still rock solid and everything works as they should. This preamp takes 2 inputs and act as a A/B switch, great for upright + electric player, or 1 input with 2 different tone settings, the boost switch just give that extra push when needed. Quality DI and simple but efficient EQ control. Comes with power adapter. $120 shipped CONUS / Canada, Paypal preferred.
