The DBTM™ is a no-compromise, dual-buffer muting interface solution that can easily be added to a pedalboard. It combines Axess Electronics' 25+ years of experience and knowledge in providing guitarists with consistent direct to amp tone and feel regardless of what's connected between a guitar and amp.

Included are 16 different filters. Choose one that matches the plugged-in direct to your amp's tone, the loaded down by your current pedalboard tone, or choose any other filter in between. Whichever you decide on, rest assured that the DBTM will NOT load down your guitar's signal.

The discrete Class-A circuit has an input impedance and other finely tuned characteristics which mimic that of tube amplifier inputs. It'll safeguard, strengthen, and prepare a guitar's signal for whatever follows on a pedalboard and in a rig.

It presents a guitar with a dynamic and ideal load that remains steadfast — resulting in consistent tone while still allowing the guitar to breathe and feel, as if it were plugged directly into the front of a beloved tube amp.

The high-headroom line-driver has superb capacitance drive capabilities and can drive very low input impedance loads (as low as 600 ohms) — which means extra long lengths of cable or daisy-chained passive or isolated splitters such as our IsoPlus™ or IsoFormer™ series will never be an issue.

For extra long cable runs between a pedalboard and a back-line amp, with extraordinary noise immunity, use a balanced ¼" TRS cable (up to 330ft./100m long) between the DBTM and either an IsoFormer RCV™ or IsoPlus™ (immediately in front of the amp).

User Manual

When silent tuning, the audio mute occurs at the TO GT-FX jack, allowing for effect trails. The TUNER output jack is muted when not tuning. If you prefer the TUNER output jack to always be on, please contact us prior to ordering.
