Now a 2 time fea owner with the addition of the dual band comp, I have the de-cl also. Just amazing quality. The dual band is even better than the de-cl, with the ability to control the 2 frequencies my sound have never been better. Thank you Frank!
Thanks for the feedback and support!

I have started using the Photon in a higher gain role, not quite fuzz, more distortion. Even still, a growler boost switch would be amazing here too instead of the octave. It was a dirty always on pre for me for a while there.... what a great circuit.Don't let all this love blind you to the fact that we still need a FEA Bass preamp PRONTO! With a Growler like boost option.....
I am so seriously right now Frank..... the Photon fuzz with blend all the way up and gain all the way down is unreal as a pre. Add a Growler like boost and we are in heaven!!!!!
I could also do a 125b/top jacks Photon with no second footswitchOk - seriously - Photon Fuzz owners you have to try this.
- Drive min
- Bite min
- Level to taste - just a little volume bump is what I am doing
- Dry max
- eq to taste
- ANCR min
- octave off
Tell me that isn't one of the greatest preamps you have messed with in a while

I'm thinking of trading my Opti Fet for a DE-CL. I remember that was the one that I dug the most. I like the Opti, but I feel like it compresses a bit too much of my signal unless I have the gain wide open and the threshold all the way up. It clips really hard otherwise. Plus I never use the side chain option. Honestly, I don't even understand how I'd use it. Maybe I'll hunt down a used one and just have both...
I just ordered this a lithium powersupply. And I still waiting for it, but I'm posting this because frank ask me to. it's 500ma has a meter read out. can be charged from a generic micro usb.. could be used pedaltrain or other v-spot accessories. like a an iso pump..etc. if is were modded to double the voltage would cool if anyone can do that! the meter show the time it'll power the pedals for, the voltage draw, and percent of charge

So this showed up yesterday. I had taken the last year off from playing/gigging and sold almost all my pedals including my DE-CL and Diamond BCP-1. I did a gig a few weeks ago and was sorely missing having a comp and had been on the look out when low and behold I get an email that I had been on the waiting list for a Opti-Fet. Thanks past self for looking out for me.What seems to be your trouble with the side chain?I only wish I were wiser about using the side chain. Love my Opti-Fet.

Frank, this thing is awesome! Thank you!
I'm a bit out of practice from playing and tweaking and at first I thought it sounded too dark then I realized I was running the threshold way too low and once I figured that and dialed in the attack speed I was in heaven. I played with it for a while and then looked up some setting posted way back in this thread and I was in the ballpark but it gave me more info to work with. Absolutely love the sidechain eq. I really like being able to back off the compression on the highs to keep so bite on that top end when playing aggressively. This pedal makes my bass sound so pro and polished.
It adds a nice fattening effect not unlike the Diamond but that pedal always seemed to have a bit of a low and fair amount of high end roll off so the Opti-Fet just sounds bigger to my ear. I always perceived the Diamond to have weird upper midrange boost but maybe that was me...anyway I don't miss that, I like have more top end with the Opti.
Being that I usually like things on the clean side the warmth switches didn't interest me...until I tried them. Again, it sounds great and I'm further impressed. It's so subtle I struggle to describe what it adds but it sort of makes the notes feel a bit more exciting or burly.
The bridge pickup in my J Bass is so much more usable thru this pedal. It gives it more meat, tames the bark and even things out so the top end can come thru. Sounds so much less boxy and more warm and 3D.
Again, thank you Frank for such an amazing product.
Thank you for the great feedback!!
The warmth circuits in the Opti were designed to distort like the high-gain FET circuit of the original class-A FET output amplifier of the first design. It is subtle, but I feel that it sounds really close to the original 100% class-A FET audio path with the warm switch 1 on. This was my attempt to "Bob Carver" the functions of a different amplifier topology.
