    Hey, folks,
    I have a pretty big pedal board (about 10 pedals) and I have a buffer at the beginning of it. I'm thinking about getting a preamp pedal just to get some more tone shaping... can I ditch the bufffer pedal, now, since the pre will be at the start of the chain? Is there any advantage to putting the pedal at the end of the chain? I do get a bit of tone degredation and being able to eq it at the end would be nice. If I put it at the end, should I leave the buffer at the beginning of signal chain? Thanks.

    BUMP for some mojo.
     
  3. I'd say that you should keep the buffer at the front end, UNLESS you have effects that rely on the PUP to load/sound right (some Muffs, for e.g.,).

    At the other end, if you absolutely NEED something to regain your signal or shape it, maybe something like an MXR M81 preamp. It has Bass and Treble controls, as well as a semi-parametric Mid control (and Input and Output controls).

    I used one before getting an Ampeg SCR-DI and Tronographic Rusty Box. I switched it out only because I actually wanted more of the sounds that the RB and SCR provide, rather than a straight Hi-Fi sound, which the M81 is pretty good at.
     
  4. I like having a buffer at the beginning of the signal chain and some sort of preamp/tone shaper/conditioner at the end of my signal chain. Currently my buffer is an [sfx]microThumpinator but for many years it was an MXR Noise Gate Line Driver DI that I bought new in 1979. I like having a tone shaper at the end simply for convenience, so i don't have go to my amp for volume or tone tweaks.

    All good to know, thank you! I'm thinking of getting the Xotic, although if someone has some other recommendations, I'm all ears.

    The Xotic Bass BB Preamp? It's definitely more of an overdrive/distortion than a preamp.

    When l ran 19 pedals on my board l had a tube buffer at the end and it worked well and l was running five different preamp pedals

    well, it is working like a buffer.
     
  11. I've always thought a buffer needed to be as close to the bass as possible, if not built into the bass.
    Isn't the primary purpose for having a buffer, to lower the Impedance so that the bass is not impacted as much by cable capacitance?
    I am strictly talking about just the buffer function and disregarding other features that may come with some pre-amps/active systems.

    I've got a BrightOnion one for when I'm not using my wireless.
