well i tot there r quite a few..
there's the radial ones..
n there's the proco ones..
sweelee has got some hotboxes..
in fact every music shop has some brands..
u can go to hifi or mics shops where there r plenty of them to choose from..
what exactly are you looking for?
i can actually supply u the proco n radial ones, if u r interested..
try looking around first.. n look at the specs n see what you actually need

JDI MK3 (S$310) BBE DI-1000 (US$250 approx S$430)..
D1-1000:
The DI-1000 is perfect for touring sound applications and recording studios, yielding excellent results with active or passive bass guitars, keyboards, and both acoustic and electric guitars. The DI-1000 is the ultimate means for transferring musical instrument signals direct to a mixing console.
The DI-1000 is a high quality direct box with applications both in the recording studio and on the road, designed to withstand the most demanding situations. It can operate as either a passive impedance matching device via the Jensen JT-DB-EP transformer, or as an active DI where the Sonic Maximizer circuit can be engaged with the signal still balanced at its output by the Jensen transformer.
Above all, the DI-1000 was designed without compromise, with paramount imporance placed on maintaining the highest sonic integtity. No competitive high-end DI unit can deliver the clear, pure and natural sound that the DI-1000 can.

Radial JDI Passive Direct Box
• Jensen Transformer equipped passive DI
• 100% isolation eliminates ground loops
• Virtually zero phase & harmonic distortion
• Exceptional signal handling
• High common mode noise rejection
The Radial JDI is considered by many to be the world’s finest direct box. It is a passive DI that employs a Jensen isolation transformer for optimum audio performance offering outstanding linearity at all frequencies, combined with extraordinary level handling without introducing distortion. Being completely passive, the plug & play JDI does not require any powering and has the unique advantage of eliminating 60-cycle ground loops. This makes the JDI a definite favorite with informed audio engineers. The JDI is great for guitars, bass, and keyboards and is particularly adept with high-output, broadband instruments such as active instruments and digital keyboards. The JDI may be rack-mounted using the J-Rak and is also available in a stereo (2-channel) version called the JDI Duplex and the 6-channel rack-mountable JD6.
JDI Features & Functions
The Radial JDI is a passive direct box that employs the world’s finest Jensen JT-DBE transformer as its main drive engine. The Jensen DBE transformer employs a laminated nickel core that has the distinct advantage of low-permeability. Permeability (see 'Transformer Distortion' side bar) is a term that describes the metals ability to become magnetized and demagnetized without retaining any magnetic memory. When one considers that full bandwidth audio is made up of a series of fundamentals and harmonics that range from 20Hz to 20kHz all of which ‘move’ in tandem, disrupting their relationship is not a desired effect! This underscores the importance of a very high quality transformer and our decision to use a Jensen.
The JDI's internal I-beam shell
1. Welded I-beam construction makes it impossible to torque the PC board. This virtually eliminates cold solder joints - the No.1 cause of system failure in the field.
2. An innovative ‘slide-in-place’ XLR trace makes it possible to use I-Beam girder construction.
3. The JDI uses a Jensen transformer for distortion-free performance. The Jensen features a nickel core for best signal transfer and minimal loading.
4. A military-grade PC board is employed for maximum wear and tear in abusive environments. Welded steel standoffs ensure the PC board will not shift.
The Radial JDI is characterized by a distinctive book-end design. This has the advantage of protecting the switches against damage from abuse by providing a protective zone on both input and output panels. A heavy duty baked enamel finish resists scratching while a full-bottom no-slip rubberized pad stops the JDI from moving around and ads both mechanical and electrical isolation.
Inside, the JDI features a compound, welded ‘I beam’ construction that protects the sensitive electronics from outside stress. This makes it impossible to torque the PC board, assuring years of trouble-free performance. The internal skeletal frame is locked together with 4 hex screws.
The input panel features a ¼” instrument input and traditional thru-put. An innovative ‘merge’ function allows the thru-put to be converted to a second input to allow stereo to mono summing. This is often used to interface stereo sources such as keyboards or CD players in live shows where audio channels may be not always be plentiful. The JDI also sports a -15dB pad to interface with higher output levels.
JDI input panel
5. A -15dB pad allows super hot inputs such as that from a CD player to be connected and balanced for long runs.
6. The Merge function turns the input and thru into a passive mixer to sum stereo feeds to mono at the XLR output. This saves valuable inputs on the mixer!
7. The input connects to the instrument.
8. The thru-put is connected to the instrument amplifier. The JDI has a high input impedance to reduce loading.
JDI output panel 9. Our book-end design creates a protective zone around the switches & connectors for best protection!
10. A heavy-duty baked enamel finish for excellent durability and great looks for years! 100% 14-gauge steel construction.
11. The XLR balanced mic level output provides 100% isolation for runs to 1000 feet without appreciable noise.
12. A polarity reverse switch flips the polarity from the AES standard Pin-2 to Pin-3 on the XLR and is used when combining sounds that may be out of phase.
13. The ground-lift disconnects the ground path to the transformer at the XLR output. This is used when a ground path is made at the input side such as with a keyboard.
14. The parallel speaker interface option introduces a second -30dB pad with band-pass filter to emulate a 12” guitar speaker.
15. A no-slip full bottom pad reduces mechanical vibration, improves electrical isolation and keeps the JDI from moving around on busy stages!
The output panel features balanced 600 Ohm XLR connector with pin-2 hot following the AES specification. A polarity reverse switch toggles pin-2 and pin-3 to allow the JDI to interface with older non-AES equipment and for creative tinkering. The ground lift switch disconnects the XLR pin-1 ground from the JDI for 100% input-to-output isolation.
Finally, a second -30dB pad may be engaged that, when used in tandem with the -15dB input pad, allows the JDI to be connected in parallel with a speaker. This, for instance, allows the engineer to ‘tap’ the sound coming from a guitar amplifier speaker ‘post distortion’ thus adding another creative dimension. This unique function incorporates a speaker emulation filter circuit that rolls off highs and lows to more closely approximate the sound of a 12” driver.
