Title: Installing a Metropolis digital effects loop PCB
Post by: Pete1950 on October 09, 2024, 01:22:24 pm

I need to know where to connect the input and output wires to an AA1164 Princeton Reverb ckt. A simple drawing or explanation will suffice. Thanks.

What do the instructions say?

I've installed a few in amps with LTP PIs, but none with cathodyne PIs. Instructions written for LTP PIs only. An internet search yields essentially nothing.  Pete

Can you post a schematic of the loop and the instructions that came with it? (I saw the instructions are for a LTPI.)

So, if it goes in between the coupling cap from the last gain stage and the input of the PI, I don't see how it would make any difference whether it was a LTPI or a Cathodyne. But then again, what do I know?

I'm hoping that it's that straightforward! I'll give it a shot. Thx.  Pete
