Top Mounted Everything! And RRR v2 discussions!

Top panel mounted jacks
top panel mounted power supply!
it must be the best kept secret in the pedal building industry.
because if the other builders knew about it, they'd do it as well.

So much easiness.

I use my Super Tri Fuzz->Sunny Day Delay->Mellowtone CC/DC because they're all top mounted jacks and sound AWESOME.

You guys are going to hate me... my prototype for the upgraded RRR doesn't have top mounted anything. *runs for cover*

I really wanted it to... I tried everything I could think of... but I think I'm going to have to break down and do side mounted jacks. I never thought I'd ever even consider it!

You gotta do what you gotta do!

Thank god I got a Miniberator TMJ FTW!

how BIG is the bigrrr gonna be?

[Gilmourish]

bigger than you can ever imagine >.>

I really really really want the upgraded RRR to fit into the same size box as the previous version, the Hammond 1590BB size. I'm working on 2 layouts, one for the 1590BB size and one for the 1790NS size, but I'm shooting for the 1590 size. I love the challenge of fitting the most stuff into the smallest box but ultimately I'll use the size that sounds the best and builds the best.

6 jacks, 1 power jack, 5 pots, 1 rotary switch, 1 LED, and 1 momentary stomp switch is the goal!

I'd prefer a 1790NS with top mounted everything





6 jacks = stereo in + setero out + expression in + xx??

xx = place to put your penis.

Pretty close, Kev! (Jared, not so close, but still a cool idea)

So we'll have 4 jacks for true stereo in and out, 2 separate audio paths through the pedal. 2 audio paths means that 2 expression inputs are needed, a left and a right, if a person wants to control both at once. So the 5th and 6th jacks are a right and left expression input that can be used in mono, separately, or used with a stereo expression to control both at once, in stereo. The problem is finding a proper stereo expression pedal that will work but I'm on it!

This is the prototype plan anyway, I need to get a box built up so I can test a few things that just can't be tested on a bread board.

[Blurillaz]

how about dual exp pedal intputs so we can have different trem speeds ala Only Shallow?

[oinkbanana]

couldn't you buffer a signal and double it up so that one expression pedal could control both sides at the same time?



& you could make one expression in for level
and the other expression in for decay?
and you could put a toggle on each expression in for "left only/right only/both"

Now we're talking! This interest me, more discussion needed...GO

The problem with the mix control is that it's not the kind of signal that can be doubled or buffered like you mean... depending on how the control works you can get away with what you describe, or at least run the control in a different way that can control 2 pots with one signal, but not the way the RRR is set up.

The mix control is a 10k pot with the dry signal on the bottom lug, the wet signal on the top lug, and the mixed output to the level stage on the wiper. For stereo, you need two pots, or a dual ganged one, a pot for each path through the pedal. I just can't think of a way to have one stereo expression pedal output control the two separate pots. I had a circuit on the breadboard that controlled the mix in a different way and worked with one expression pedal output but it involved totally changing the audio paths. I had to run the audio through 2 OTAs and then I could use an expression pedal to vary a control voltage that would affect both left and right channels independently. Worked pretty slick except I couldn't get it to go fully wet or fully dry and much worse, the two extra processors in the audio path totally affected the sound quality. They added noise, hiss, and changed the tone audibly... had to Pasadena that plan.

If the mix was controlled by a control voltage it would be much easier, but it's a resistive divider of 3 circuit paths and I just can't come up with a way to control both channels at once with one expression pedal. I'm still pondering it a ton but I've sort of given up hope and resigned myself to having to use 2 expression inputs for stereo users.

Decay control via expression is possible, assuming I can make the decay control work.. it's one of the things I need a working prototype before I'll be able to say yes for sure... but assuming it does work, the problem is that the expression pedal would have to have a sweep of exactly 10k and no more. 12k and the reverb engine would stop working. Some expression pedals would work, some wouldn't, but the ones that wouldn't work would totally disable the pedal and I don't know if that's an acceptable thing or not.

Expression control for level on a reverb pedal just doesn't seem like an important feature to me.. I think it's cool if a reverb pedal has some level available but I don't think it needs to be controllable by foot.

But man, the whole expression control for mix situation... I've been pondering it forever and I'd love to come up with a better solution than using 2 expression jacks and trying to find a proper stereo expression pedal, which I haven't yet and I've got the best 3 available I think. Kev, come up with a single expression pedal mix control and you can have a bigberator!
