The Weehbo Mastiff Distortion is a "take it in your teeth!" kind of pedal. If you're a fan of hot-rodded Marshall, Jose Arredondo mod , Cameron mod 'n co... in short, anything associated with big British sound, then you've come to the right place!

The Weeboh Mastiff adopts a compact box with the usual Gain and Level controls, active 3-band equalization and a mini toggle switch that allows you to choose a specific frequency range for the mids. The Mid Freq switch allows you to correct different frequency ranges: 2kHz left, 500Hz center and 1kHz right. Inside, it's very very pretty, with PCBs and components of excellent quality and a precision assembly. German quality!

Small detail that is important, the pedal can be powered by 9 or 18V. What does this change? Well in 9V you have a softer sound, a little warmer. At 18V you have more headroom and increased dynamics. We leave the choice to you and it couldn't be nicer! We still recommend that you supply it with 18V to have the maximum possible graouh!

Once plugged into the clean channel of a Two-Rock Studio Signature (clean channel of excellence), the first thing that strikes you is how quiet the pedal is. Despite the almost exponential amount of gain present within it, it manages to maintain a low noise level. It's beautiful! A lot of "boutique" manufacturers could take some seed from it :-)
With the gain at 12:00 and the flat EQ, it already sends the ball rolling in the 70's / 80's hard-rock style with an assertive upper midrange and a sharp upper end of the spectrum. The Mastiff generates a very "imposing" low end that can be controlled very precisely thanks to the impressive on-board active EQ. The highs are quite wise until 2:00 p.m. From there, we start to cut hard, which by pushing the gain and by activating the Mid Switch on the central position, you will switch to the big sound typical of Hard Fm and other Metallica 'n period 80's. Whatever the setting, the EQ is incredibly precise and can really change the character of the pedal. The mid range is particularly interactive, it can be hollowed out for more modern, straighter styles, or pushed for more warmth and fluidity.

The Mastiff Distortion is a fun, easy to play and very flattering pedal. Its density, its massive side and its sound signature make it a success. The fuzz harmonics, you have a wall of sound under your fingers and that's all you want from a high-gain pedal!
