  1. well from my learnings, the current rating of the inductor has a lot to do with it. I don't understand the science of it, partly because i end up reading this stuff after a long day in work, but i've also found that lower rated inductors (I have a bunch of 0.1A ones) also seem to struggle at higher voltages. I'm currently using 1A ones, and although they're a bit bigger, they're not excessively big and they work great.

     

    I would guess that it probably would limit you at multiple tubes, but I'm going to be trying it with two submini tubes in due course. The submini tubes I have are rated for maximum current draw of 100ma each, where as the 12A#7 tubes, I believe, are 400ma each.

  2. Prototype #3

    Yes, I know it isn;t the neatest of wiring by a long way, but it's a prototype, and if it all pans out, I'll be going to a PBC. Fuck perfboard. fuck perfboard forever.

     

    Made a few changes to numbers 1 and 2. The cathode caps have been changed to make it friendlier to bass, this means slightly more lower end when working with guitar, but nothing excessive. Changed the cathode resistor values too, so it gives more gain which is more suitable to the 12AT7 tubes I'll be using. Added 2 LEDs for each half of it.

     

    The point of these 3 prototypes is to rule out any problems and have a few prototypes to see what people think of them. I do plan on doing a few clips of this one, but not till after 15th of may. If the general consensus is that it's good, I'll do a run of 10.

  3. yeah in an effort to distract myself from the more pressing matter of studying for my professional architect's licence, I've been trying to figure out a few bits and pieces with the tubes I have. I'd love to crack into those 3 reverbs, but matching consistent levels of gain with the different impedances of the reverb tanks is proving to be a pain in the arse.

     

    Moral of the story, fuck tubes.

  4. EBS is great stuff because it works so well on bass; anything that works on bass ought to work well on guitar. The other way around: not so much.

    However, the other way around I've yet to see: most guitar pedals really lose bottom end fast. :(

     

    Yeah the more I look at the one I've made and compare it to the valve drive, I think mine will be much the same. At the cathodes, there's two caps that, put simply, add gain to selected frequencies. I think I have it setup to add gain primarily to the mids for guitar. Now that being said, it wouldn't be that difficult to change a few values so I get the same gain but not restricting the frequencies that get all the gain, so its more uniform.

  5. Bass chaps, I have a question about bass effects.

     

    I was looking up about some of Sigur Ros' recording techniques, and how they play live etc. I noticed that a lot of their live gear is from EBS. Lots of valve drives, compressors and distortions from EBS. The valve drive is of interest to my question, because it appears on the pedalboards of both the guitar and bass players in Sigur Ros. Pedals like the valve drive and compressor are pitched as being "universal" in that they work just as well for bass as they do for guitar.

     

    What I'm wondering is how common is this? Or, how well in general do guitar effects work with bass? The reason I'm asking is that I'm considering doing a run of the tube pedal I recently built. Tone wise, I tried to be as transparent with it as possible. Its neither treble nor bass heavy, and when designing the circuit, I made a conscious effort when selecting caps to avoid picking values that would shift its characteristics in the direction of guitar or bass. Ideally, I'd like this pedal to be as friendly to a bass setup as it would be to guitar. So from a bass player's point of view, I'm curious as to how well guitar pedals transition to bass?

  6. I don't have the money for one now, but early next year I'm emigrating and I'll be getting a whole new rig/selling the old one. I'm looking at a way that I can be efficient at having a rig adaptable for both guitar and bass. Kemper with a Poweramp and a nice cab seems to be a way that I can do just that.

  7. Hmmm.... The problem is that its for a spring reverb. Bonus unfortunate part is that the only place I can really mount the spring tank internally will be on the same side of the box as the switches. So I'm trying to find an option for the two switches that will be quiet. One switch is for the bypass, and the other is part of a feedback loop.

  8. crowella, do you know about/have you used, switching relays for bypass? I have a pedal lined up that needs a footswitch bypass solution that doesn't click like a normal 3pdt does when you stand on it.
