Absolutely!! I use mine for exactly that. 2 band EQ, leave gain at zero and almost pin the level. Pushes the green crunch into awesome land. Will be looking at a custom OFA version soon!!
Ive got a BM. Its great value/$. It shapes the tone though, it cant really do a 'transparent' boost, in particular, the most neutral overall tone in terms of setting its two tone controls, comes with some loss of high treble. Its great if the amp is a little harsh to start with. I reckon its also a good match in tone and price with MG Marshalls.
They work pretty well. My band's last single was recorded on a DSL15H with a bad monkey boosting the red channel. Gain 0 Tone to taste drive DIMED!
From the Monkey please That removes the Nasaly tone it has and basically opens it up, sure will compliment the DSL much better once you rip that C5 off, or you could just clip off one end of the C5 so it does not sit into the circuit....will help if you'd like to go back to how it was before....
A bit of googling tells me that cutting C5 will remove the mid boost that makes it sound like a TS. You can replicate that without cutting up a Monkey though. The Screamin' Blues sounds more open & is voiced VERY similar to a DSL. If you want the mid boost, go with a Monkey, if you want a "flatter" response, try a Screamin' Blues, they can be had for the same money as a Monkey, but they have more output level & can push the front of the amp harder.
Not only does it remove the nasaly/midrange as you mentioned, but it also opens up the pedal a lot, in terms of frequency response, I wish I had one at my desk to show you how it changes in response on an oscilloscope... Check this clip of my modded BM. You may get an idea of what I mean. https://www.youtube.com/watch?v=8fyizPhT6LA
purchase one of Mikes OFA Tube Boost Plus pedals and you'll never need anything else to boost your DSL. Trust me! I ve played this setup on numerous huge stages with Quiet Riot, Great White and many more, and always get compliments on my sound. Easy and simple! He is "HOT TUBES" ON HERE.
Very good OD at a very good price. Use mine quite a bit on the green channel of my DSL40C and also on the clean channel of a Hot Rod Deluxe to add a little grit.
When i get some t-shirts made up here soon .... I'll have to send you one for all your Positive feedback etc etc . Thanks so much Damon !!
Have you done this mod yourself ? As far as i was told & seen ... the circuit board in the BM is all SMD , so unless your a very skilled guy with the soldering iron , this maybe a task only for the pro's .... Food for though ... not trying to scare anyone away from attempting this mod , but SMD circuitry can be a bit of a challenge even if your tooled up for it .
