joegarcia Posted January 14, 2008 Share Posted January 14, 2008 Hi, Hoping to add a blend knob to my looper. I tried using a 400k pot and wired the input to the circuit, output and return to it and it sort of works but it gets really quiet in the middle where I would want to st the pot. Any ideas why i get this volume loss? Do I ned a different resistance pot or have I just wired it wrong? I have the return on the middle lug and the in and out on the outer two and tried all the other combinations. Quote Link to comment Share on other sites More sharing options...

The normal circuit is more complex then you have made as a dual gang pot will be required in order to get the best results with a passive design. An active blender will give much better results.

joegarcia Posted January 14, 2008 Author Share Posted January 14, 2008 Ah bugger. I worked out that its only one effect in that chain that needs the blend and it's a boutiquey type unit made by a local guy so i may just get him to mod it for me. Thanks for your help.

joegarcia Posted January 21, 2008 Author Share Posted January 21, 2008 Hi Dave, On another note. Don't suppose you'd be up for making a small active blend circuit I can fit in my looper? Is this an expensive option? Quote Link to comment Share on other sites More sharing options...

I am not into designing one off SS effects as I would not turn it into a product so yes it's an expensive option. Sorry. Dave Quote Link to comment Share on other sites More sharing options...
joegarcia Posted January 21, 2008 Author Share Posted January 21, 2008 Ok no worries. Wasn't sure how easy it would be. Quote Link to comment Share on other sites More sharing options...
