mcnach Posted May 10, 2012 Share Posted May 10, 2012 I love my EHX Bassballs. In fact, I just bought another. I had a nano version originally, and just bought the larger USA version which has been modified to give you access to the two internal trim pots with two externally mounted knobs. I love it. But I find it a bit frustrating that as you increase turn the main knob to the right, the volume increases, especially with the distortion switched on. This pedal would improve a lot if there was a way to adjust the final level. I can put it in a loop of a Boss LS2, which is what I normally do when I have a pedal that gives me trouble level-wise. But I was wondering whether it would be easy to add a level control. I haven't seen this modification described, so I suspect not, but... maybe I'm wrong!

paul_5 Posted May 10, 2012 Share Posted May 10, 2012 stick a 250K pot going to ground just before the output jack - should send any unwanted signal to ground. Quote Link to comment Share on other sites More sharing options...
mcnach Posted May 10, 2012 Author Share Posted May 10, 2012 essentially like a passive guitar volume? I thought of something like that, but I am not sure what kind of value pots would be appropriate, and fear it would change the tone too much while turning the volume down (a compromise I could maybe live with, I can do a test before drilling any extra holes and see if I like the results), so I was wondering more about an active option... probably much better to use the LS-2 for that, eh?

umph Posted May 10, 2012 Share Posted May 10, 2012 a 100k lin would do the job, a limiter after it would be even better Quote Link to comment Share on other sites More sharing options...
Bigwan Posted May 11, 2012 Share Posted May 11, 2012 (edited) Limiter? Rubbish!!! It's an easy mod. Don't put the pot just before the output jack - that'll control both effected and uneffected signals. You want to put the volume pot between the output of the circuit and the footswitch so you're only controlling the effected volume. Done this a few times with mini qtrons (actually have one in my work bag returning it to Gareth Hughes of this parish today - although for this pedal I removed the rotary switch, hardwired the pedal to low pass and put the new volume pot where the rotary switch was - stealthy, makes the pedal much more useable and there's no change in tone that I can hear).

[/quote] aha! indeed, that sounds like a great mod to the micro QTron with its volume bump... and I only ever used it on Low Pass anyway... I must try this with the Bassballs... when I gather the courage to open it up and mess with it Quote Link to comment Share on other sites More sharing options...
