General Questions / Re: Dirtbaby Dry/Wet
September 13, 2017, 06:10:18 PM
Do it this way:

Remove T1 and wire a 50kB pot to it instead. Remove C38 and put a 10k in its place. Jumper pads 3&2 of the Blend pot on the PCB (but don't solder pad2 yet - you need to connect something else there.

Remove R47. Solder lug3 of a 50kA pot to pad1 of the Blend pot on the PCB. Connect lug1 of the new 50kA pot to ground. Solder a wire to lug2. On the other end of that wire, solder a 10k resistor. Now solder the other end of the resistor to pad2 of the Blend pot on the PCB (the one I told you not to solder before).

Illustration below. This still isn't perfect because the two 10k resistor act as voltage dividers when one pot is grounded but it will get you much closer to what you want. You could make R2 a 22k or 47k instead to reduce this problem...it just depends on how high you set that Level control (BTW - you don't need to remove or fix the Level control for any of this). Also, you can use a 50kA for pot1 as well...it's just a matter of preference. A 50kA will allow for more subtle blends of the wet into the dry signal.

Can anyone tell me why this isn't giving me individual control over the wet and dry signal and they are still interactive with one another?  Is there a better way to accomplish what I am going for?

Because you are grounding the signal when you turn one of the volume pots down. You need resistors to prevent this. Use a 10k off the wiper of each volume pot, and connect the other end of each resistor to R6 (or skip R6 and connect them both to OUT).

Here is the draft of the Tractor Beam BOM/Shopping list. I have a bit of debugging to do on my build but I believe this list is accurate.

Global Annoucements / International orders are delayed
September 12, 2017, 12:05:42 PM
It looks like most of the international orders I've dropped off at USPS in the last 7 days are not being updated through the USPS tracking system (they show as 'awaiting receipt'). This is likely due to Hurricane Irma. Virtually all international orders go from Nashville to Miami before departing to their destination. And, I expect Miami hasn't been productive these last several days. But all packages have been dropped off here in Nashville so they do have them.

Anyway, if you received shipping notification in the last week and USPS is not updating your package, don't panic. It's just a matter of waiting for normal operations to resume which will hopefully be soon.

There's not enough information provided to give any sort of help. Without knowledge of any part substitutions used, voltages on the build, pictures, etc I can't offer much advice.
#2706
It's possible I wrote down incorrect voltages (I've certainly been known to do that). I can dig mine out and double check.

That's not very surprising, honestly. But...I mean...c'mon. Do the Reverse Centaur.

Kinda gassing hard on a Starfire IV electric now. I love the bass so much it seems like the perfect compliment. Anyone own one of these? Not into the Bigsby but the fixed bridge version seems right for me.

Tech Help - Projects Page / Re: Excel Calculator
September 09, 2017, 12:54:22 AM
Here's an updated version of the Formulas Excel sheet. I've added the following:

LC Filter (inductor/cap filter)
Resistor Drop (for finding the correct resistor value and wattage it requires for a specific voltage drop)
LM317 (for outputting specific voltages based on two resistors with the LM317)

Examples for each in the first row.

You rock an e-mu x-board too?

I got it for a great deal back when I lived in Austin (I think I paid $100 for it?). It's actually perfect for using with VST. Midi and power run through USB so it's quite convenient.

I'm actually kinda surprised. Did you sub another TL072 or a different type of op-amp? Where did you get them from?

I tried a delay with bass for a brief time.  Worked ok with new strings and the mids dialed back.  Otherwise, I got too muddy or stepped on the toes of the other guitarists.  Could've been the bass, the amp, or the player.  :P

We were a 3-piece at the time so there was lots of space to fill. I used my old Digitech PDS1000...no tap tempo! And the Whammy was usually set to de-tune mode. The best compliment I ever got as a bass player was someone said I was the "Tony Levin of Dallas", lol. Definitely not deserved but appreciated.
