MK III Tight Arse

[Cave Passive Pedals]

Hi Guys,

Yeah, I know, I've been away with the fairies lately and not answering your queries. I am sorry.

The good news is I've been working on the LPF and HPF powered circuit, the third design of the Tight Arse series, and have now got enough data to put together a prototype for Dave (aka Bobbybdazzler) to test.

Those that play stand-up / double bass will be happy as the input impedance will be 5 meg (possible 10 meg) to suit piezo pickups. Also, each filter will have 2 poles (slope of 40dB/decade (12dB/octave)), the same circuit as the "Tighter Arse" (MKII) but with a second order attached.

The difference between the MKIII Tight Arse and other similar products on the market will be the cost, country of origin and a boost/overdrive circuit.

Cheers
Heath

What will one of these cost?

What will one of these cost?

I'm trying to keep it under $100... hopefully.

Wow, LPF, HPF and active boost in the same pedal???? Can’t wait to try it out.

[BazzBass]

Yep I'll haves me one of them when the time comes

Looks like another one I'm gonna have to sign up for

Count me in, too!

[slave]

Yep I'm interested in this one too, count me in!

[Imaidan]

Also really interested. Any kind of vague ETA? Early or mid next year?

Cool - will it have a feature where the frequency can be moved up or down for each filter? (Hope I've used the correct terminology here!!!).

Yep, same as TA MkII.

I've gone sideways a bit with this design, hence the delay, sorry.

I'm now into playing 8 string guitars and have noticed a loss in punch when playing the 6th, 7th and 8th strings on all three 8 string guitars. The Death Metal 8 pole pickup design doesn't seem to lend itself well to my style of Heavy Rock switching into Country and then R'n'R/Blues/Jazz. So, I've started to redesign the Tight Arse into a pedal that can separate string frequencies and add boost/frequency change where necessary, also (at the same time) cutting out unwanted/unnecessary low frequencies and high frequencies. Not sure if this will be overboard for most players until I have a prototype in my hands.

I might be on the right track, though, as I went into a music shop in Toowoomba the other day to buy a parametric eq (to see if that would be an easy way to fix the problem) and the guy behind the counter said the same thing... the 8 string pickups all have the same problem. He did mention a new 8 pole design but personally, I'm not sure if it will be as revolutionary as they reckon.

As for ETA, I'll attempt to have a prototype by early next year... maybe.

Thanks Guys, for your patience and interest... AND A MERRY CHRISTMAS TO YOU ALL!

And Merry Xmas to you and yours, Heath. I'll buy one no matter what the final specs are

[jcburn]

Thanks for the response Heath.

This does sound interesting (overkill aside ) ... especially if it covers the freq range of my 8 string bass, it could benefit greatly with some boost in the right places

Merry Xmas, Heath. and keep up the good work, mate!

Sounds great! Count me in!
