Easiest Reverb on Ruby Amp?

[kevinng]

I'm a total newbie.

I'm looking to build a Ruby amp, and am planning to add reverb.

I'm looking at PT2399.

What would be the easiest modification to the Ruby schematics to add reverb with PT2399 or other chips?

What resources/examples can I look at?

Thanks so much.

What do you expect from your reverb? Because a PT2399 is a delay chip, the reverb will really sound sparse

You could take a look at Merlin's Equinox.  This uses two PT2399s and gives you something reverb-like (I've gigged with an Equinox).  But you won't get reverb with a single PT.  Or else look at something like the Chasm reverb (deadastronaut).  This uses a BTDR-2.

Bolt either of these (or similar) to the front end of the Ruby.  I'd recommend you breadboard your solution to be sure the result is what you need.

as others have said a pt2399 wont cut it with reverb....(the belton brick has 3 x pt2399 within it)

if your building it into the same unit as a small amp, i have the timestream reverb

which uses the belton brick, and will easily fit into a 1590b, instead of the chasm which will only fit into the larger 1590bb

nice easy build too.

as for the amp i would go for the ''champ'' tda7052a amp..it takes pedals nicely, and is very clean...

I designed up a small little practice amp and used the equinox II in it. It's ok to give some space in a pinch, but reverb really needs density. There are a boatload of FV-1 and Belton Brick designs out there. I designed up a 4xPT2399 reverb that I think sounds really nice, but it is not a simple project. I was able to fit it all in a 125B, but everything is surface mount. If you care to check it out, it's here: https://scientificguitarist.wixsite.com/home/t60-reverberator.

For DIY reverb, you really have to pick two of the following: good, easy, cheap.

The Rub-a-dub reverb is a decent sounding dirt-simple Belton Brick build, just a dual opamp and a BTDR-2 with a couple passives. Not going to blow you away with sweet sounds, but will do the trick for a practice amp.

Just my thoughts; but I'd consider building the reverb unit as its own pedal, rather than install it in this ruby you're planning. I mean, it's just a ruby with a 2" speaker.

Have a look at the pictures thread. People here treat their work as art pieces! Very inspiring stuff.

I have a little Danelectro Hodad amplifier.  It is LM386-based with a 9V battery and two small speakers.   It has push-buttons for reverb and tremolo.  The "reverb" is PT2399, but seems to include the sort of filtering that smudges the slapback-range repeats so that they kind of sound reverb-ish.   With a better amp, a solitary PT2399 would provide a rather unsatisfying reverb, but on a very simply amp with tiny speakers, it's good enough and doesn't draw an unreasonable amount of current.

Thanks so much guys, I'd take all your replies and study them.

I've noticed the single PT2399 based circuits can at least do a decent slap-back effect (Rockabilly). Of any x2 PT2399, I only know the Equinox mentioned and that does do well given its simplicity and can be convincing.

Merlin's Solstice is another 2x PT2399.  Also gigged with this.  In the mix, it's perfectly acceptable.
