This doesn't sound like a HJ Bass/Treble issue...
When I started doing some research into the DSP (reading that great Tome), I discovered that EQ changing is supposed to be accomplished by register bank switching, with a soft audio mute active at the time... (ie register bank A is active, when we change the EQ, we write the new values into register bank B. Then we SAM, switch the active register bank, and then un-mute. Next change we write to bank A again...and so on)
ISTR thinking that this wasn't being done in the empeg - the active register is updated directly, without a SAM. If bank-switching and SAM had been used originally, then we wouldn't have ever had a problem with HJ bass/treble pops...
So if you try to modify values quickly, expect to hear some pops and clicks. If I ever get around to re-working HJ bass/treble to use the DSPs built-in controls, then I might look at reworking the EQ code to implement b/s and SAM. But it's not high on my list of priorities at the moment - I have another project brewing..........
