We designed Q-tune to fit in either 1590b or 125b, the PCB with top DC and top jacks is the same for both. While they aren't that different, the 125b is bigger. I'm wondering if anyone will want the 125b or if everyone will opt for the 1590b.

  • 125b: 66mm wide, 122mm long, 39mm tall
  • 1590b: 60mm wide, 113mm long, 31mm tall

Thread 'Just curious: 125B vs 1590B?'

I'm torn between using 1590B cases w/side-mount jacks vs 125B with top-mount. The 125B would be narrower and offer more internal space, but there's something I love about 1590Bs.
I just saw the 1590B with top-mounts, and looks like the best of both worlds - just looks like a TIGHT fit.

I'm curious to know if anyone still chooses a 1590B over a 125B, and why?
 
For comparison:

Left to Right:
a) Turbo Tuner ST-300 Mini - 1590A, 39mm wide, 93mm long, 31mm tall (with side jacks is ~70mm wide minimum)
b) Peterson Mini - custom, 46mm wide, 90mm long, 32mm tall (with side DC jack is ~60mm wide)
c) Q-tune - 1590B, 60mm wide, 113mm long, 31mm tall
d) Q-tune - 125b, 66mm wide, 122mm long, 39mm tall
 
What’s the inside of the 1590B look like. I like the size but I literally want to throw it by the time I’m done building a pedal that size.
 
Will it be possible to order without an enclosure, and have a tayda drill template for it? While it certainly looks nice, one of the biggest appeals of diy for me is that it looks the way I make it look, and being able to do my own UV print over a powder coat color of my choice would be a big deal imo.

Good point. We will certainly make the Tayda drill template(s) available. I’ll look into a “no enclosure” option.
 
I get most people will want the 1590B size, but I'm after the 1590N1 size (125B as most people call it).

Bricksnbeatles makes a good point, for having a Tayda drill template (why not both a B and N1?), for Tayda, however...
I don't use Tayda's drill/art services currently, though I intend to eventually try them.

I'm happy with a raw enclosure (pre-drilled of course) shipped with the kit, then I can paint it whatever colour I want.
There's not much room for graphics with the large screen, so I'd be happy to just have a plain paint job, colour of my choosing.



Are you shipping kits with Hammond enclosures?

Tayda drill and UV is currently our enclosure path. I'm open to others, but the price is hard to beat.
 
I did builds using 1590B and top-mount jacks for a while (see @MichaelW's excellent 1590B Top Mounted Jacks guide). But I got away from that, because if you want to use cables with right-angle connectors, they have to be the generally-more-expensive low-profile type. IOW, I found that the common "pancake" style jacks were too big, and would interfere with the DC power connector. (Obviously, straight jacks don't have this problem.)

That's cool that the same drill template works for both enclosures, but IMO it comes at the expense of not getting the full benefit of the larger 125B/1590N1.
 
Here's a comparison of the width:

TurboTuner with pancake jacks = 67mm wide
Peterson with side DC jack = 60mm wide
1590b with 3 top jacks = 60mm wide

Polytune and 125b shown as bigger versions.

So Peterson has a great tuner, but Q-tune's screen is a LOT bigger for the same width (which is what most pedalboards care about)

Can we see a pic of the 1590b internals vs the 125b? I am curious to see how tedious it would be around the jacks.

This is not the production PCB, similar schematic with RAMP and C9 deleted from production PCB. But the jack spacing is the same. 30mm between audio jack centers.

As far as tedious, it's not tedious at all because all 3 jacks are soldered to the PCB. Takes about 30 seconds to install the PCB assembly into the enclosure, and about 30 seconds to put 3 nuts on (2 audio jacks and 1 momentary). No wiring necessary, except for the momentary switch and that's connected to the PCB assembly. It takes me 2 hours to assemble the PCB (obviously I've done it a few times). Most people should expect 3-4 hours for assembly.
