Wampler Tumnus Overdrive and Boost Guitar Pedal
Safe and secure checkout
The Wampler Tumnus is a compact overdrive and boost pedal built for players who want that sought-after transparent, mid-pushed drive sound in a pedalboard-friendly format. It works brilliantly as a low-gain overdrive, a tone-shaping boost, or an always-on pedal to add presence, harmonic detail, and a little extra push to your amp. Wampler describes it as a faithful take on that famous mythical overdrive circuit, housed in a very small enclosure with Volume, Gain, and Treble controls plus buffered bypass rather than true bypass.
One of the reasons the Tumnus remains so popular is that it is easy to place almost anywhere in a rig. It can tighten the front end of an amp, add body and clarity to another drive pedal, or act as a standalone overdrive with enough gain for a wide range of styles. Recent reviews and user feedback consistently highlight it as an excellent always-on pedal and a strong option for pushing an amp that is already close to breakup.
Its compact size also makes it appealing for crowded pedalboards. If you want the feel and response associated with this style of overdrive without giving up much space, the Tumnus is one of the best-known options in this category.

Why Choose This Pedal?
The Tumnus is a strong choice for players who want a pedal that improves the feel and response of their rig without overwhelming the original sound of the guitar and amp. Used with the gain lower, it can add thickness, cut, and a more polished feel. Used with the gain higher, it moves into rich low- to mid-gain overdrive territory that still keeps notes articulate. That flexibility is one of the main reasons it has remained one of Wampler’s most popular pedals.
Another big advantage is the buffered bypass. Unlike a true bypass pedal, the Tumnus keeps a buffer in the circuit, which many players use to help preserve clarity and signal strength across longer cable runs and more complex pedalboards. That makes it useful even when the pedal is off.
It is also one of the easier pedals in this style to dial in quickly. With only three controls, it is straightforward on stage or at rehearsal, but still gives enough range to cover boost, edge-of-breakup, and fuller drive sounds.
