"Would you like to own one of the best sounding 303's on the planet?

She is a fully working gem and has been living in a smoke free studio for years.

She has recently been serviced by Brian Castro, the best synthesizer tech in all of Los Angeles and maker of the famous x0xi0 mod for the x0xb0x.

She has custom blue and Red LED's along with being modded to accept midi by Colin Fraser. Just look him up online to find out more ;-)

Truly a one of a kind beauty..."

x0xi0 Full mod kit for x0xb0x is now available

via Brian
"It's been 18 months since I showed the [not so] final prototype ;)

I've made several improvements to the original feature set and added some very useful new features. The Full mod kit consists of the Top panel mods and the Rear panel mods. The Rear panel mods, also known as the I/O & Overdrive kit, is the part that I started selling in July 2008. This is a subset of the Full kit. Hence, the kit is available as a Full kit or the Full kit upgrade for those who already have the Rear kit and just want to add the top panel mods. The general look of the kit is white on black accented by red & blue LED’s. The final overlay is still being test printed and has not been ordered yet, but will be very similar to the rendering in the picture shown.

This is not a simple mod package, it is a very extensive addition to the x0xb0x. The kit build is medium difficulty. If you built your x0xb0x you should be able to install the kit. If you want to get a general idea of the difficulty of the project you can download the Install Manual for the Rear kit here [9.16M PDF].

All the controls on the mod can be zeroed to return the x0xb0x to stock. The kit uses only high quality parts from Alpha, Bourns, C&K, E-Switch, Nichicon, NKK, Rean etc.. and includes everything necessary to build and install the mod:

* new rear panel pcb (sits above x0xb0x I/O board)
* new top panel pcb (sits above x0xb0x mainboard)
* new aluminum rear panel
* new machined aluminum top panel
* new overlays for the rear and top panels
* all parts needed to complete the mod
* all necessary wire & cable
* all necessary hardware to install the pcb’s and reassemble the x0xb0x.
* Install manual with step-by-step instructions for stuffing the pcb’s and installing the kit.

The new features are:
New Controls:
VCO1 Level Control

Please be advised there will be a (7) week lead time from the time I receive payments until I receive all parts, finish the documentation, and pack the kits.

New Avalon Bassline Synth & Sequencer From Abstrakt Instruments - Details & Price

Abstrakt Instruments is a new company from the creators of the x0xi0, a heavily modified x0xb0x that is considered to be the ultimate x0xb0x.  The Avalon is a new instrument and is not based on the x0xb0x. Full details will follow in time, but for now you can get a good feel for what it is via the pics. Click on each for the full size shots. Note there is a white, silver and black version.  Also note the cartridge slot and swappable 24db Transistor Ladder Filter and 12db State Variable Filter cards. There's Dinsync IO in addition to MIDI IO, and extensive CV IO.

You can find an interview with Abstrakt Instruments' Brian Castro previously posted here.

Update: some initial info from Brian (press release is still to follow):

"ok guys, we just got done at NAMM. If we don't sleep for 3 days straight the official press release will go out Monday for those of you who weren't able to attend NAMM and get a demo in person. There will be more content coming as everyone starts to upload more pics and edit videos. For those who can't wait for the NAMM content and debut of the website here are some bullet points of the basics.

The avalon bassline synth is an analog monosynth based on the TB-303. It combines a 100% mirror of TB-303 RevD mainboard together with a panel board containing additional analog and digital circuitry.

Uses all original spec parts of the original TB-303 (transistors, caps, IC's, diodes, transformer, etc..) together with a BA6110 VCA with current gain calibrated to match the original BA662.

Fully backwards compatible with the original TB-303 (actually works with an original TB-303 CPU).

Sub oscillator has saw, sqr, and tri both -1 and -2 oct.

The cartridge slot is for filter carts which can be hot-swapped and used in place of the internal TB-303 filter.

Additional analog controls include sub/ext level control, filter tracking, accent decay, vca decay (goes full off), AD utility envelope with bi-polar modulation of the VCA and VCF.

I/O on back includes CV & Gate In/Out, accent sweep cv out (amplified and normalized to 0-5V), filter cv input. Audio out consists of saw and sqr out (+/-5V), external input, and vca & filter outputs.

Sequencer control has TB-303 pitch/time modes as well as a new realtime mode making use of the the step led switches (yes those are switches). Too many features to list - browse the panel to get an idea. patterns can be 64 steps in length with numerous time signature options. There are 448 internal patterns and 56 tracks. These can also be saved and loaded via sysex.

Sync modes are internal, MIDI and DIN, and it outputs both MIDI and DIN Sync. Also has USB-MIDI, and synth can be played externally.

Extremely high build quality including custom pots, german key switches, and 4-piece steel enclosure.

Can't comment yet on price except to say it'll be under $1000US."

"This was my first effort in getting together a live electronica set for a small local Halloween Art Show. Its not perfect but you can see where it is coming from. Most basslines and leads were played live on hardware. Drums were sequenced in Maschine and muted live.

Sorry for iPhone audio, the base is lacking. [SoundCloud below]

Gear List:
Maschine Ableton Plug-In for Drums and vocal samples [mostly from old commercials and movies]
Future Retro 777 for first two songs basslines
x0xi0 for the later songs baselines
Kaossilator Pro for leads and Arpeggios
Vermona VSR-3 for spring reverb
Mackie PRO fx8 for mixer"
