Guitar/ukulele equipment chain question....

    For my school, I just bought a Line6 Spider IV 75-watt amp. It is solid state. What would happen if I put the Groovetubes Brick in front of it as a tube pre-amp?

    I use a dimarzio acoustic pickup on the inside of my acoustic uke. I plugged my baby into the amp, and there was LOTS of feedback at even low levels on the amp.... would using a DI box help remedy this or no?

    If I used said Brick from said uke to said amp (without DI), would this reduce or increase feedback? What about with DI?

    Remotely related: I like ukes better because there are less strings.

    I'm not sure how you visualize the Brick connecting to the input of the Spider.

    I assume the DiMarzio ends with a common 1/4" plug. Which you would then plug into the 1/4" input on the Brick. The Brick's tube tone and Gain (with a capital G), would come out the XLR output - while the 1/4" output is just an unamplified "thru". So I'm not sure how that would help.

    Mr. Brick can give you up to 55dB of gain via the XLR, which to me - sounds like the last thing you need anyway.

    I think you gotta check the settings on the amp, and/or the position of the pickup. Using a DI into a PA might give you more control than using a guitar amp.

    Do you know anyone with an LR Baggs pre-amp / DI for an acoustic guitar? Something like that with EQ, plus a notch filter might be useful.

    Good luck!

    These guys make soundhole covers and they are beautiful, they will make them in any size and this cuts down feedback bigtime.

    JG, wow those are amazing looking.... I will look into them into further detail.

    DVD, you are probably right in your analysis. I just wanted some tube warmth, without a tube amp. Reading that out loud makes me song stupid. I am looking for my uke to scream like a John Frusciante electric guitar.

    I can dig it. Doesn't sound stupid at all.

    Unfortunately, it will be an uphill battle all the way with short nylon strings and a hollow-body. Those soundhole plugs JG linked to look interesting, I might have to get one for my acoustic. I don't like the rubber plug I have now. I only use it in rare and extreme circumstances. It definitely tames feedback on a high-volume stage - but takes a lot of the tone with it. (not unlike an aggressive notch-filter would). Those carved plugs might be a happy medium.

    If you want to wail on 4 strings, you could take the PUSA approach and just put any random number of strings on a solidbody electric. Those two guys didn't have more than 5 strings between them, but had some quirky catchy songs.

    Or you might consider one of those mini solidbodies.

    Either way sounds like fun.
