  • How good is the Harrison Labs Reverb processor?

    Does anyone here have experience with the Harrison Labs Reverb processor? I saw it on eBay and had fantasies of adding it to an older Allen.

    It seems pretty simple, but the Reverb on the Ahlborn Galanti SL-300 is like this and I thought it was pretty good.

      when I can, I'll get one. If they're excellent, I'd love to hear the MDS through one! If I could have had that 705 I wanted, I bet it would have been nice.

          a 2nd opinion

          I hate to be a bore, but I have to get my 2 cents in.
          I've not heard one of these and never intend to.
          That being said, the possibility that some guy in Colorado could make a better reverb processor than what you can buy for 100 bucks on ebay from a real company (Lexicon, Roland, TC Electronics) is totally, completely laughable. It would be like reading a headline "16 year old whiz kid in Berkeley invents more powerful ipad, will sell for only $30"). Now he might have taken an existing piece of technology and come up with some good presets for it. Good for him. I did that two with the reverb processors I owned.

            Hi, I have purchased two of these devices, and they transformed my Allen 301B from an instrument I could barely stand to play to and enjoyable experience. The 301B is in my home, a very dead room accoustically, carpet, drapes, small, about 12' X 15' size room. After my success with the (Reverb Unit - called DSP Ambience Processor) I added the Traveling Wave Generator tm stereo and the difference is phenomenal). I play a smaller digital allen at church, Model 201 (no card reader), that prior to my upgrade of my home organ was OK. After upgrading my home organ, I found it stressing playing at church and have added both the DSP and TWG at church and everyone wanted to know when we got the "New Organ." The devices are well worth the money and the difference in my playing technique (keyboard touch and sound produced) are much closer to a pipe organ in a very resonant cathedral. Both devices are adjustable to your environment and personal likes. After re-reading the installation material, I doubled the devices as described in the literature and have fallen in love with my organ. I practice more, it's easier to play, and sound wise, improves the electronic sound as the Traveling Wave Generator (TWG) slightly shakes up the pitch to help smooth out the harsh sound of the tones created from a single pitched pitch generator (MOS 1 system). Personally I don't think you can go wrong with the purchase, and I highly recommend adding both the reverb (DSP Ambience Processor and TWG Traveling Wave Generator) to improve your sound. BTW, they work on electronic organs other than Allen too. Tomm G + home organs Allens 301B and 601D, church Allen 201B.

              I have been curious about the TWG for some time. For a 2 channel MOS organ, does it affect each channel separately? Harrison Labs really ought to have some audio examples on their site to help sell the items.

                HL may make a good product, but their web pages are terrible. The "Technical" data on the products don't even state what inputs and outputs exist and what kind of connectors are used. The pictures don't have enough detail to discover that, either. The TWG manual does more or less give that information, but it's not well expressed and the connection diagrams are awful. (I realize that the instructions are intended for owners of Allen MOS instruments, but I think they could be a lot better, both for MOS and for other brands.) The manual for the DSP Processor doesn't even have a connection diagram. Presumably, both devices have some kind of controls: the TWG manual does vaguely cover its controls, but the DSP manual doesn't say a peep about it.

                The devices look well built in their pictures. As radagast indicated, some sound samples ("before" and "after") would certainly assist one in determining if they would do the job desired. And considerable improvement of the technical manuals on line would also help.

                  Harrison Labs Reverb (DSP Ambiance processors) and Traveling Wave Generators (TWG)

                  Hi, sorry I took so long in responding, been busy preparing for Christmas Eve and Christmas Day Services. The literature from Harrison Labs shows an RCA input for both the flute and main channels. I know it makes my organ sound great. Please go to this link HTTP://www.hlabs.com/manuals/TWG/index.htm to read the documentation. Notice at the bottom of the page you must manually go to the next page (same goes for printing). I have actually doubled the devices on my Allen 301-B , that is two Traveling Wave Generators (TWG) and two (DSP) Ambiance processors as shown on this page HTTP://www.hlabs.com/manuals/TWG/ind...es/Page442.htm. The improvement in sound almost knocked me off the organ bench. It is such fun now playing Widor Toccata from Sym # 5, or Louis Vierne Finale from First Symphony. Actually anything is thrilling on this instrument afte the upgrade. I'm sold on these products. Instructions on adjusting the products are also in the installation material. I feel the two devices work best together, unless your room has an echo of greater than three seconds. I would first add the reverb DSP Ambiance Processor and then the TWG. If you install, shoot me off a note, I'd be glad to pass along some tips I've learned during installation and adjustments during the home and church installations. Good luck. Tomm G + home organs Allen 301B and 601D, church Allen 201B. All connections are standard RCA female jacks so plan for patch cords, also determine if you require expression pedal isolators also available from Harrison Labs. I noticed an earlier thread about H-Labs documentation and just sent Stan at H-Labs an email. The installation file for the Reverb (DSP) is missing all but the first page. It should be corrected tomorrow. Tomm G + home organs Allen 301B and 601D, church Allen 201B.
