Product Description
- Inspired by custom culture The JCM800 Modified is inspired by decades of guitarists who have personalised their amps in search of more gain tighter response and greater tonal flexibility.

The dynamic attack rich midrange and authoritative low end are all present giving players instant access to the classic Marshall tones we all know and love. Added switching options build on this foundation allowing smooth transitions between tones and making it easier to dial in sounds that sit perfectly in a mix without losing the amp&rsquo
