Silent killers.

Spider IV 15 and Spider IV 30 are wolves in sheep's clothing. They can do something that many other amps can't: they can produce great tone - including scorching high-gain tones - at low volumes. They're ideal for late-night jamming, small spaces, and any place where size, weight, and volume are a factor.


Stay focused.

To get the whole story of Spider IV amplifiers, you need to turn one around. All Spider IV combo amps feature a perfectly tuned three-quarter closed-back cabinet. This provides a tight, punchy, focused response that you can't get from an open-back cabinet.
The Spider IV 15 and 30 guitar amps are packed with real-time and professional presets to take your sound to the next generation
Our guitar amps are the best for a reason, with built in tuners - you'll always sound your very best
Tune up.

You'll always sound your best with the built-in tuner. No need for an external tuner or additional guitar cables, this invaluable tool is integrated into the amp's front panel. Activate the tuner with the push of a button.


Speak up.

Celestion® guitar speakers are world renowned for their exceptional definition, clarity, and feel. A 12" Celestion® custom speaker helps clean tones sparkle and sing, creamy overdrives respond to the intricacies of your picking, and searing brutal tones launch themselves from the cabinet.*
