Sold. Trace Elliot bass preamp in great condition for its age, these are well regarded and with good reason. Trace Elliot logo lights up when the unit is turned on. All knobs are present and everything works a treat, with the exception that the Graphic and Pre-Shape switches can occasionally not change with the first touch (common fault with the GP11). I have fixed this issue by adding a generic footswitch and cable (both included). This works really well. There is slight damage to the plastic nut of effects loop send, does not affect functionality. Collection/tryout welcome or UK insured postage for £14.00
