the BOR is proven on bass, so it sounds good to me. it lacks the boost switch is something i could live without. the subs switch doesnt sound that useful for bass. but for a cheaper price, it sounds like a good deal.The ZVex Vextron Distortion features the same distortion circuit as the Box of Rock with the addition of a gain boost switch and a sub frequency control switch. If you have been wanting the sound of a Marshall JTM45 non-master volume cranked up but haven't been in a position to spend $2000, the ZVex Vextron Distortron could just make your dreams come true. The knobs are self explanatory and control Volume, Tone and Drive. The sub switch adds increasing amounts of sub from 1 to 3. When switched to 3, the ZVex Vextron Distortron has the same sub level as the Box of Rock. The Lo setting on the gain switch gives you the same gain as the Box of Rock, while the Hi setting gives you increased gain.
so they say it works on bass. the subs switch could be an attempt to draw the guitarist market onto something that functions very similarly to the mammoth. it has the input inpedance control which the active-unfriendly mammoth lacks. ive read some lukewarm reactions regarding the transistors though.The ZVex Vextron Mastotron fuzz is based on a heavy silicon fuzz design using a 2N2222 transistor ala Jimi Hendrix. Zachary Vex says it has a ‘bumble bee’ quality that stays solid for all settings. Knobs on the fuzzy little fellow are Volume, Tone, Pulse Width, Fuzz and Relax/Push. The Pulse Width knob allows you to change the wave form from square wave to narrow pulse waves and everything in between. The Relax/Push knob adds source impedance to the signal that enters the pedal. This allows the ZVex Vextron Mastotron to soften the input being sent by active pickups to maximize the fuzz effect and to adjust how the pedal reacts to how you play. There is also a Subs Switch that lets you dictate how much sub content is added to the signal. If you have been searching for a fuzz that allows the complete control over wave shape, sustain, attack, decay and texture of the fuzz, the ZVex Vextron Mastotron might be the ticket.
buy aye, even if it looks good its still only on paper. they could use the same design but cheaper components. it could be cool if you don't already have a BOR or WM and want to get that tone, but if you ALREADY have the 2 you might not dig the downgrade
