This latest addition to the acclaimed JCM2000 series is a smoker! The Marshall TSL 60 amplifier head deals up 60W and an all-tube signal path (4 ECC83s in the preamp, 2 EL34 power tubes). It also features footswitchable spring reverb with separate controls (for clean and crunch/lead). Channel controls are also dual; one set for clean (gain, bass, mid, treble) and another set for crunch/lead (gain, volume, bass, mid, treble, and a Tone Shift switch to scoop mids). Other controls include a master volume, master presence, and a deep switch providing a tightly focused bass boost that fattens the sound dramatically. There's also a mix control on the back panel effects loop. Includes a 5-way LED foot controller that switches between channels, and on/off control of the reverb and effects loop.
