Re: Onboard reverb help needed!

The general consensus I've seen online is that a single half of a TL072 doesn't quite have the current output capability to drive a tank well and most people think it sounds week. The Rod Elliot circuit and others reccomend using a higher current output opamp (like a NE5532) and running both halfs ...

Re: Onboard reverb help needed!

I would move over to one of the Accutronics Belton solid state reverb bricks . These can be powered off of the filiment once you rectify it. That sounds really cool. Would love to know more... any links handy? Have you done this? It sounds like a better idea. Also this might be exactly what I need:...

Re: How to add the dry signal to this reverb circuit?

Although I may be misunderstanding your request, the blues jr reverb takes a clean signal, adds reverb and then lets you use the 'reverb' potentiometer to decide how much of the reverb signal to insert into the main dry signal. I.e. the circuit already does what I think you're asking. If you have t...

How to add the dry signal to this reverb circuit?

Here's the Blues Junior reverb circuit.

Assuming I have a dry signal wire, how would I make it so that the "Reverb" pot is a wet/dry mixer instead, so that I can get wet/dry out of a single wire again? Where would I add the (bypassing) dry signal to this schematic?

Re: Onboard reverb help needed!

I failed to mention, Rob's circuit doesn't work very well in this case. It's noisy and the reverb seems weakly-driven. It lacks "punch". I'm hoping that a few resistors and caps can be swapped for better values, but I don't understand the circuit well enough to know what I'm affecting or how! 4E is ...

Re: Onboard reverb help needed!

I have, yes, but it's over my head, I'm afraid. I already have the layout built in DIYLC, just need some help plugging in the right values:

Onboard reverb help needed!

Hi all, I hope I've come to the right place for this... I'm adding a solid state reverb to my Mojotone Studio One. So far, I've added a small 36V transformer and a power supply for +/-16V for the op amp. I have a 8EB2C1B tank, compatible with the Fender Blues Junior, so I'm trying to copy the reverb...
