18 Watt TMB

The 18W TMB (Treble, Middle, Bass) is one of the many variations of the original 1974 Marshall 18W amplifier. It has two channels. The TMB channel has volume, treble, middle, bass, and master volume controls. The normal channel has only volume and tone controls. The TMB channel is voiced more like a Plexi while the normal channel is cleaner.

Use either 6V6s or EL84s: EL84s are the standard option on these kits. 6V6s are smoother and have less gain, less treble, and more bass when compared to the EL84s.
The same chassis can be used in a head or combo.
