The only thing I used to put in the loop of a SS amp I have was a passive attenuator because it was too loud and I couldn’t adjust it quiet enough. The LBM is louder than the NYC so you shouldn’t have any problems if you run it direct into the amp.

A side note: For effects powered by batteries a dying battery will make pedals clip. I had this problem once and I went through every modulation pedal to find it, it was my small clone running on 6 volts. It sounds like a light OD or a non true bypass pedal.

I pretty much think Fender makes the best tube/spring reverb so they would have a lot to live up to IMO. I’m not sure it would be worth it really as the Fender unit is as good as reverb gets IMO.

Set your MS on with the filter so you can hear it sweeping, then slowly turn the trim that you messed with, adjust it very finely until it sounds right. If it doesn’t sound like its effecting the filter, turn the filter to a minimum and set something else to the maximum and adjust it again, do this till you find what it effects. Either that or send it to Howard Davis for repair.
In future don’t turn trims that aren’t user friendly, I see far to many people ruining their effects because they think they can get it to sound “better”, if this were true, the companies would set it like that for you as they want their effects to sound the best they possibly can.

The polychorsu is no where near as lush and deep a chorus as the small clone, if you buy one for its chorus you will be disapointed but if you buy one for its chorus/flange/weird ass noises you’ll be pleased. IMO, you MUST own both!
