Overall Rating 5/5 (4 reviews)

It delivers the sound I was looking for, not only for the overdrive tones but also for beautiful glassy highs of clean tones.

Its a mini Plexi! Great amp based on the vintage Plexiglas circuit. Takes a bit of dialling in but produces sweet classic tones. Its very loud too! Don't be fooled by the 20W rating, you can easily gig with this amp. Works best when jumping both channels & is a great pedal platform.

Although it's only 20 watts, the Marshall Studio Vintage Head is loud and produces an amazing lead tone. By blending the sound of the High Treble and Normal channels using a patch cable I can play clean or with varying degrees of crunch simply by adjusting the volume control on my guitar. Sounds great with my PRS guitars and Fender Original Telecasters.
