Need Advice - Custom Analog Delay with Boost

[Bio77]

I recently got to meet the guitarist of a band I'm super into, and offered to make him a pedal.  So, he is currently using a MXR Carbon Copy set with a short slap-back delay.  He uses it for lead sections of songs.   He mentioned that it was a too clean sounding.  The other ask was that he used to have a MXR Micro Amp and would turn on both for leads.  He ditched the micro amp because hitting both pedals was distracting. 

My plan was to build an Aqua Baby (DM-2) and add the micro amp or other clean boost inline so both are activated by one foot switch.  So, since the clean sound was a problem, I'm wondering if a preamp would be a better choice?  Or maybe a transistor based boost?  What do you guys think?

I'm not familiar with the input section of the dm-2 and how it would react, but with other circuits I've had great experiences with the lpb-1 style boost. Happy to chuck you a pot-sized-footprint pcb gratis if you want.

I would think you'd want the DM-2 first you avoid a hot signal going in to it.

Thanks guys!

That would be cool, thanks!  Let me figure out how I'm going to box it.  I was thinking of fabbing a foot switch version if the parts count was low enough. It would be handy.

I was thinking that too,  I'll mess with every thing outside of the box before I commit.

You could possibly adapt the DM-2 input to replace the Si buffer with a JFET boost, and make the boost part a pot or switch. But, there's no ready made sort of project that I know of that does so. It's an interesting idea, for sure.

Thanks, Brian    I'm going to try breadboarding some stuff and combine it with the AB.  I have a couple of populated boards that need a home.  Not sure, I want to mod the working ones, might try the LPB-1 first.

I have an EHX Deluxe Memory Boy and it has a gain knob that is boost after delay, maybe check that one out.

Thanks, I will definitely check that out.
