Hot cake topend???

[jubjub]

I have been using a crowdther audio hotcake for years but something has happend to the top end. It's sounding a bit dull. I notice it alot when I'm using other overdrives in comparison. Does anyone have a schematic or know what I can do to get a bit of sparkle back into this once delightful pedal?
