Plexi 45 Joins Retro-King's Hand-Wired Amp Line

Retro-King's "Plexi 45" is a replica of the mid 60's JTM 45. Unlike the reissue, this amp is hand wired point to point on a vintage style turret board and is built to the exact specs of the original (Retro-King adds a 100 pico cap across the normal volume for added clarity).

This amp uses the early "plexi" tone control values along with the standard preamp values. You can also order this amp with the optional negative feedback control adjustable from the stock 27k to 47k. This will give an increase in gain. The "Plexi 45" is also available in a 2x12 combo.
