GGG 6 band eq troubles

[hendrix2489]

hello, i have been working on the 6 band eq at general guitar gadgets.  I got everything working but, the led is dim and the signal is a little distorted.  the bypassed is fine .  but the effect is distorted

2.Name of the circuit =GGG 6 band eq
3.Source of the circuit (URL of schematic or project) =http://www.generalguitargadgets.com/pdf/ggg_eq6b_sc.pdf
4.Any modifications to the circuit? No
5.Any parts substitutions? If yes, list them. no
7.What is the out of circuit battery voltage? =>9v

the slide pots work well, and so does the trim

a power supply issue could explain both, low power = dim led and less headroom.

checked power, voltage is fine.  i desoldered and resoldered some caps and the pots, and the distortion has pretty much gone away , except a little distorted bass response

[hendrix2489]

does anyone have any ideas how to cut this distorted sound
