Dual Channel PRO Preamp
TWO Channels on TWO MONO INPUTS

Dual Channel Pro features the same specs as the other K&K Preamps, but features two independently controlled channels to allow you to blend two pickups or other sources. With its 1 MegOhm input, you can use the inputs for two piezo pickups, mics, or magnetic pickups using the two separate ¼" phone jacks. It features external volume controls for each channel, along with individual internal treble, midrange, bass, and gain trim controls for each channel for fine-tuning. The main output delivers the blended signal. Extremely compact, approx. 4 3/8 x 3 3/8 x 1.5 inches.




Dual Channel PRO Preamp ST
TWO channels on ONE STEREO INPUT

Dual Channel Pro features the same specs as the Dual Channel PRO Preamp, but features a stereo input and specialized dual outputs. As with the standard Dual Channel PRO preamp, you can use the input for two piezo pickups, mics, or magnetic pickups; however, it has a single, stereo (TRS) ¼" input jack. Like the other, it features external volume controls for each channel, along with individual internal treble, midrange, bass, and gain trim controls for each channel for fine-tuning. Another difference is in the unique output jack options: the main output alone delivers the blended signal - but if you also plug into the second ¼" output, it automatically re-routes each input individually to those two individual outputs, so you can send each pickup to separate amps (or board channels).Extremely compact, approx. 4 3/8 x 3 3/8 x 1.5 inches.

K&K Sound preamps are full-range, and suitable for use with any pickup. Due to their 1 megohm input impedance, they are ideal for piezo-based and magnetic pickups. Yup, I've been known to use my Pure Preamp with my old '71 Fender Precision fretless bass, for that "active" sound without making nasty new holes in that sweet old bass.



Do you need a preamp?
You might not, but it's good to know for sure! Refer to the information I've put together concerning impedance matching and using piezo pickups with "normal" amplifiers.

All K&K Preamps have the same basic specifications:

  • Frequency range 10 - 30,000 Hz
  • Input Impedance: 1 Mega Ohm
  • Output Impedance: 3 K Ohm
  • Average Current: 3.5 mA

Bob--I put the Eurosonics (I purchased sometime ago from you, just got around to installing them) on. Frankly I was afraid of the transition from steel strings, and as you told me "they don't look like they'll work but they will". You were right, they don't look like they work but they do.

Your help and honest real-world advice is very valuable and I join all the others in thanking you nearly everytime I deal with you.

I use a piezo-magnetic blend. It's good to see you now offer a magnetic pick-up (significantly cheaper than the one I have), I think blending with the two channel K+K preamp is the way to go. I play at rock band volume sometimes with a blues/roots rock band and I wouldn't want to do that with just a piezo. The two-channel pre-amp (mine's mounted behind the tailpiece) gives you the ability to plug in and play quickly when you're playing through backline. It's a pleasure to not have to fiddle with a bunch of cables and boxes when you want to get on and off quickly and easily.

Back to the Eurosonics, I bought them to try to get more rockabilly slap going but I have to say the combination of a magnetic/piezo and the Eurosonics is great even with straight pizz. You get a more traditional sound, the thump, the quicker decay, --and it's warmer and less "very-long-scale-fretless-electric" sounding. I'm not a latin player, but I tried a latin tune at a rehearsal and in my opinion this combination would kill for latin in the hands of the right player.

Thanks for the good advice you provide on preamps, and thanks for the quick service on the K&K, which arrived in time for three weekend gigs. The preamp makes a world of difference, even with my older Fishman BP 100 pickups, which are positioned under the bridge feet. I'm able to get a much warmer and controllable sound than I could by going through an external EQ. For the time being, at least, I'm off the hook for investing in a better pickup, and when I do decide on one, I'm sure the K&K will still make a big difference. Thanks again, Jene

Hi Mark,

I received the order I placed with Gollihur Music yesterday. Thank you. I was surprised to receive it so promptly. I wanted to give you an update on my problem.

I installed the Jargar Medium strings on my plywood "work" bass this morning. I was pleasantly surprised at the initial tone, as I expected the strings to be a little brighter since they are steel core. However, they sound warm and wonderful. The E string seemed to have a little weaker sound than the other three, but not enough to cause concern. I "toyed" with the "Full Circle" adjustment and I believe that on this particular bass the best sound seems to be when the pick-up is turned at about a 45 degree to the bridge foot. Thank you for that tip.

I was extremely pleased with the K&K dual pre amp. The magnetic pick-up and the full circle both sound great. I did a little "tweaking" as suggested by the manufacturer and I now feel that I have finally achieved a good amplified sound. Once the amp is set for the best sound, the Jargar strings sound equally good with the bow or pizz. with the harshness gone, which was present before.

Thank you again for your suggestions. I am 64 years old and have been playing double bass and electric bass since 1964. I have a room full of equipment from old vintage stuff to some fairly new amps and basses. However, I have tried just about every combination of amp and amp settings you could think of with less than satisfactory results. I could never quite find the sweet spot setting. I also own a 4/4 Pollmann double bass that I have set up for orchestra and community theater work. This bass also has a "full circle" installed as well, but usually is played more with the bow, so once it is EQed, I have had little issues with it. It is so resonate, however, that is unsuited for amplified work in high volume settings.

To make a long story short, I have been dealing with amplifying the double bass for a long time and now, finally I am able to get some of the problems worked out. I am a bit of a purist, and really do not want to go to an EUB personally. I know that and EUB is a good compromise, however.

I will be working with the big swing band tomorrow, and I am really looking forward to having the bass blend with the band while still cutting through with a nice warm tone.

Thanks again!
