Does anyone manufacture a buffer with adjustable level?

[PAULYC2]

To narrow is down a bit, the Cameron CCV has an insert loop and it works perfectly with a Boss SE-50 effects unit. When I use other pedals, they are too dark. I’ve tried using the MXR buffer, the Empress buffer and they don’t help. So far the best unit I’ve used is a Suhr mini mix2... but it increases the signal a lot. When I use it, and insert the cables into the loop, the volume jumps. I’ve asked Suhr if there is some way to add an output level pot, but they didn’t want to help. So I did a search for an adjustable line buffer and there really isn’t anything that helps my issue.

I did try the Kleinulator, but it didn’t really help. It was cool, but just not what I wanted.

When you say “other pedals are too dark”, are you ACTUALLY talking about pedals or effects in general, because I bet IF you’re talking about true pedal effects the issue is impedance mis match with the simple insert loop, which is why the SE50 (rack unit) isn’t too dark. Are other rack units too dark ?

You could always try a Metro Loop or a tube driven loop.

Lehle volume pedal.

sounds like you're looking for something like this:

Thanks for the thought.

I have an Empress Buffer + which is very similar to the Boogie box. The empress provides too much boost for the loop.

Are you against installing a metro loop? Stock it isn't, perfect because it's designed to sit between the treble and master, and because of the master placement of the CCV, it's not perfect, but 3 component changes to the metro loop and I can assure you it's complete my quiet and transparent.

I could install a Metro Loop, but it would be a lot of work. The foot switch jack shares the same circuit board as the loop, so I’d have to add a relay and new wiring just for the foot switch, then new wiring for the loop. Also, the metro loop isn’t drop in, so I’d have to modify it to fit the current holes. I don’t dislike the insert loop, just looking for something to help with foot pedals.

Perhaps something like this would help, it’s kind of like adding a parallel effects loop.
I have one and use it on amps without a parallel loop and it works great to add in or out the amount you want to the dry signal.

This looks really interesting. Kinda like the Suhr mini mix 2 with a mix knob.

Masotti White Box is exactly that

It sounds like there's a few things being mixed up here...
The cameron loop is not buffered, right? Like the ceriatone and fortin stuff.. This would be why connecting a buffer pedal/whatever to the loop sounds bright, because you are not loading the loop output the way the unused loop circuit does which causes the treble rolloff. Buffer/pedals have a high input impedance (usually 500K to 1m) which doesnt load the non-buffered loop output, therefore dont produce the treble roll off which you are interpreting as a treble boost
.
The Boss unit is a line signal type impedance (i'm pretty sure) which is a low load (usually 20k impedance), this causes the treble roll off in a similar manner to the unbuffered unused loop which is usually loaded by the following amp circuit parts.

So it seems to me that you just want to add line level impedance of around 20k to load up the buffer output of whatever you first plug into the loop...

This makes sense. Others said it, but in a simpler way. Makes me think the Radial Dragster would help?

Interesting thing to note, some pedals are bright and some are dark in the loop so I’m assuming it just impedance differences with the pedals. For example, using a Fortin Zuul in the loop makes the amp brighter. When I pull the cords out of the loop you can easily hear a difference.

Yes that sounds right, an unbuffered loop is quite sensitive to how much load is on it. The amount of treble roll off you observe would be directly related to the input impedance of whatever you plug in, which is likely to vary a bit. I know what you mean, I have the same thing happen on one of my marshalls which has an unbuffered loop. If i plug in a pedal reverb the tone becomes super bright

Yes that Radial dragster seems like the ticket.
If i was to guess what was in that box, I would say it is a 20k resistor in series with a 500k or 1M pot placed between signal and ground. Then you could vary the input impedance of whatever is plugged in to match the line level device like the SD50 (for a low impedance, dark tone) all the way up to the usual pedal buffer (for a high impedance, bright tone).
