H & K Tube 20 unruly gain

Hi all! This is my maiden voyage here, so please bear with me...I am a novice, hobbyist-type electronics dabbler kinda...you get the picture.
I have an H & K Tube 20th Anniversary amp that I really like the clean tone of, but on the OD channel, the gain really spikes after about 1 1/2. Anything anyone can suggest ? Maybe change the pot out?? The schematic shows a 500K linear...would changing it to an audio make a difference? I've thought about selling it, but they aren't moving very well. Any help would be appreciated..thanks and God bless !!!:confused:
