Hi Zen Mod,

I tweaked pumpkin with your recommendations, I had more gain in the stage, is that possible? I reduced the gain 47k instead of 100k.

the sound is different, difficult to say ...... more clarity, less dark, very precise, less warm, more attack.

I have to hear more material, of cause I was used to the old pumpkin sound that was a bit more relaxed.....

very interesting......

the pleasure continues, tweaking frontstage of BA-1......

have a sunny day: and don´t forget

.... The more I hear with modified pumpkin music I can say To observe more details and they are better located in the soundstage. The reverberations around voices and the construction done by the sound mixer is comprehensible.

Default shortening the output for muting

Hi,

can I short-circuit the + and - outputs to ground for muting or is it not good for pumpkin?

Regards,
Marcel

Any downside to using a switched attenuator between them for volume control?

But Mr. ZM, you prefer the attenuator on the input side, right?

I'm gonna build that thing someday!!
