I'm not sure if I can ask this here or on another part of the forum but here goes;


 Is there an internal adjustment for the chorus on the MP-1? I remember from years ago something about the two trim pots inside the unit or are they for something else?




Thank you in advance Guys!

Hey DJC, IIRC yes there is some adjustment, although this is more MJMP territory....  There are some post about it, maybe do a search for chorus.

I did not realise this, I thought the trim pots were for the OD1 and OD2?  I like the Chorus on the MP1 but I never use it due to lack of adjustment.

Like RG said, you have an adjustment for OD1 and OD2, T2 is OD1 T1 is OD2. There is only a bias adjustment for the chorus (T4) but if it works, stay of it, else it could be that your chorus doesn't work anymore. T1 and T2 you can adjust if you like. T4 not .

Thank you so much for sharing this MJMP!
Would it be too much to ask for a picture of which trim pots can be adjust for gain?
This MP-1 has more gain than any MP-1 I have ever owned! Almost like it had a 3TM mod but yet it only has two tubes so I bet the trim pots are cranked, not that I mind but if I chose to lower it a bit which ones would I adjust and which direction or is it to sound and taste?


Thank you so much for your input!

Sure, now the trimpot numbers are wrong in this pic but the text is correct.
