Do you still have (and use) this preamp? I really like it, and combine it with a 1u rack power amp and a Warwick 1x12 cabinet. Sorry about bumping such an old thread, but there is very little information available about this preamp. I wish I had the schematic for it.

I did some simulations in WinISD by defining a driver based on some Peavey BW 1502-08 parameters I found at a Peavey web page, and using a 47L cabinet volume from my measurements of a TKO65. It seems that the "short vent" gives the amp a bass response peak somewhat higher than 100 Hz at the...

I wish I had the Thiele Small parameters for the original drivers in the Peavey Megabox 1516 and the TKO65, because then I could see what WinISD has to say about the effect of the short port lengths.

The problem I was suspecting was that the resonance frequency defined by the driver, the cabinet air spring and the vent air mass might become quite high since the vent air mass is low, because there is no tube. Far below the resonance frequency of the tuned cabinet, the bass response is worse...

Hi! I'm using a Peavey Megabox 1516 speaker which has a 15" driver, and the baffle has two simple triangular holes in each of the lower corners. I know about the Thiele-Small driver parameters and tuning of speakers by means of air canals/tubes, but in this case there is no tube to create any...

Thanks. I have always calculated the string tensions when I have experimented, in order to avoid disasters. Anyway, I gave this idea up. I've decided to continue to play the cello in standard fifths tuning.

Electric bass sounds in the same range as a double bass, i.e. the E-string is 41Hz. The lowest note on a traditional cello is the lowest C that you can play on a bass, i.e. the lowest C on the A-string of the bass, i.e. 65Hz . When I want to tune my cello in EADG, its E will be at 82Hz like...

Hi! I'm playing a cello tuned in EADG and I find it a bit difficult to get hold of appropriate strings. One alternative is the d'Addario H550 which is made just for this purpose. But I was wondering if strings for 1/10 double bass would also work, since the scale lengths are almost the same...

I have finally got hold of some new Roland PK-6 bass pedals. Does that mean that I can get a number? They will mostly be used to accompany myself while playing guitar or cello. At the moment they control my M-Audio keyboard, which goes through an small amp and into the Peavey bass cabinet...

Thanks! I probably want to keep the complications to a minimum, so I guess I have to go for the Roland PK-6 since it has this function built in. If I want notes above the octave, I guess I can use the transpose function.

Ok, I got word from the importer of the StudioLogic MP-117 to Norway that it does not have any autohold feature. But it suddenly dawned on me that such a feature is perhaps not needed in the MIDI controller pedals if the synth that I would be controlling would implement the autohold effect...

Does anyone here know if the Studiologic MP-117 has a "hold" feature? I've contacted Studiologic by email with this question, but received no response. I think the Roland pedals have such a feature, and I think it would be useful for me. The "hold" feature would let any note sustain...

While I will primarily use it with guitar, it just occurred to me that I still want it to fit under my digital piano stand, the legs of which are spaced at a maximum of 81cm apart. So that rules out the Roland PK-9 and Hammond XPK-200. I'm now leaning toward the StudioLogic MP-117, which should...

Thanks everyone, your responses have been very useful! Although I enjoy the old school synth bass sounds in the context of prog rock (e.g. old Genesis/Rush/Yes), my primary application for this will be to imitate a bass line in a jazz or classical context, while using a clean sound on my...

Hi! I'm considering getting some bass pedals for playing bass lines whilst playing guitar, recorder, or even cello (although the last one is probably too difficult to combine with the pedals). I know of the Roland, Hammond, StudioLogic and Moog products. Is the Moog the only one with a built...
