    Simple Attenuators - Design And Testing

    Thanks John - I'll have to decide if I'd rather have the bypass or the option for two cabs....I rarely use more than one but it's just good to know my options. Appreciate your quick response!

    Simple Attenuators - Design And Testing

    John - does this mean that if I use the bypass, that I can only use a SINGLE output instead of the two outputs? For example, if I have the 16 Ohm amp and 16 Ohm attenuator, but it's driving two 16 Ohm cabs, isn't that an 8 Ohm load? In which case that would be bad if I engaged the bypass since...

    Simple Attenuators - Design And Testing

    When you say "during playing" do you mean actually switching it while you're playing guitar, or just having the amp on? For example, if I put the amp in standby would it be safe to switch to bypass, or would the only real safe way to do it be to switch between bypass when the amp is completely off?

    Simple Attenuators - Design And Testing

    @JohnH - I just wanted to say THANK YOU for all the time and effort you put forward on this project. I was able to get it all wrapped up and tested out today and I am VERY happy with it! My scenario might be a little different than most. I have a Blackstar HT Club 50 Mk II 50 watt amp. I...

    Simple Attenuators - Design And Testing

    Sounds good - they are SUPER close to fitting. In fact, the inductor is 19 ga. instead of my 18 ga. wire, and I was able to fit those both into one lug. I might try getting a small circular file and seeing if I can very slightly increase the diameter. But if that fails I'll just glob them all...

    Simple Attenuators - Design And Testing

    I feel kind of dumb here, but I'm hoping this is a simple issue that someone else has run into and knows a way around it. There's a few places where I need to solder two wires to a single lug of a resistor. For example, on the M2 design, L1/R1/R2B all need to connect, either one lug of R2B or...

    Simple Attenuators - Design And Testing

    For the "M2" design would I be correct in assuming that either of the outputs (Out 1 or Out 2) can be used with a 16 Ohm cab (I'm building the 16 Ohm version and the amp output will be at 16 ohm)?

    This is perfect, thank you for the explanation! Got all the parts ordered, can't wait to build it and try it out!

    Simple Attenuators - Design And Testing

    @JohnH I decided instead to build the M2 version with the single inductor, that you have laid out in this post (only mod would be a single output jack instead of two, since I have a 16 ohm amp driving a 16 ohm cab)...

    Simple Attenuators - Design And Testing

    @Gene Ballzz @JohnH - Thanks for the tips! I did order 3x or 4x above the dissipation shown for the resistors (I do have a 50W amp). Good to know about separating hot/gnd from chassis, I don't have any plastic TS jacks so I'll have to order those as well. I am going with the simpler one...

    Simple Attenuators - Design And Testing

    @JohnH All the work you've done here is just awesome! I did have one question on your schematics - I'm familiar with soldering, but I had a question on your symbols you're using. Specifically, I want to make "Design C" on post #68 way back on page 4 (for a 16 ohm amp output and a 16 ohm...
