    There is no perfect ban...

    They are a revolving cast of Nashville session musicians, or so my friend that follows the band told me.  The spouse and I drove a couple of hours to meet her and her friend for a Mummies show in Punta Gorda, Florida.  The Mummies do a good live show I suppose, but it was too loud for me.  After the first number, I walked outside and waited for the show to end.

    K&M 18880 discontinued?!

    Guessing Thomann now not doing K&M is  to protect USA dealers?   Previously got K&M  and Crumar stuff from them when my usual sources were going to have to special order or  simply couldn't get.   With international shipping it was still cheaper.   Yamaha or Nord are understandably not allowed either.  

     

    Reminds me of the days when dealers couldn't sell Fender and Gibson in the same store, or Tascam and Fostex 

    I bought a Behringer X32 from Thomann at a great savings, however, the unit would have to be shipped back to Thomann for warranty repair.

    Just got an unexpected Freebie - Wurlitzer 200

    Okay, I realize I'm a little late to the party, but how did it go?  I just got a free 200 in similar condition and am about to do the same thing. :)

    Careful in there Wes, the stators (i think) have about 200 VDC on them.

     

    I had a 140 for a while.  For the longest time I couldn't figure out why tone produced from a tine wasn't the 2nd harmonic of the tine's vibration frequency. The tine and stator form a time-varying capacitance.  When the tine is at rest, the capacitance is maximum.  At the maximum physical excursion either above or below the stator -- minimum capacitance. So one cycle of tine motion gives two points of maximum capacitance and two points of minimum capacitance. That should give two cycles of change for one cycle of tine vibration. What gives?

     

    Then I worked on a Rhodes and it became clear -- the amount of 2nd harmonic is set by adjusting  the tine-to-pickup offset position at rest.  The Rhodes will generate a pure 2nd harmonic if they are aligned with no offest. I don't have a Wurlitzer anymore but I expect that the Wurlitzer tine is not centered in the stator gap. It's also not adjustable through simple means, though the tines could be bent I suppose to adjust the harmonic level.  Unfortunately that also changes tuning I think.

     

    Being me, I replaced the noisy SS amp with a single op-amp transimpedance amplifier. The input is a virtual ground. The input current equals the change in capcitance times the DC voltage on the cap (thus the 200VDC).

     

      i(t) = V*dC/dt + C*dV/dt, but since the input is a virtual ground, the 2nd term is 0. It worked great.

     

    Have fun!

    OT: Cataract Surgery and gigging

    in The Keyboard Corner

    Posted

    I got both done early in 2023. It was  surprising seeing things at their actual brightness and colors, with no haloes around street lights, and with a better vision correction, however...

    I now have posterior vitreous detachment that I did not have (or did not notice) before the procedure. The symptom is that when scanning my eyes from side-to-side, like when driving, or reading on a monitor, there is a cloud that passes in front of my vision after the eye rests at the new position. This happens all the time and sometimes it is quite annoying and interrupting. It is most noticable in bright environments (bright sun light, while driving). Occasionally I've taken to driving with one eye closed. I understand there is surgery available.

    It has been almost a year since the surgery and although hasn't gone away, I suppose I am starting to ignore it, kind of like tinnitus.

    I need a drum mat recommendation

    in Hit It!

    Posted

    Ultimately, I ended up finding 3x5 indoor/outdoor door mat at a local big-box home store that has worked out really well for this small e-kit.  Of molded construction, it's made of recycled polypropylene/rubber, is quite dense, and weighs about 12 lb. The kit's spikes can penetrate the weave but not the rubber backing, which keeps things from sliding around while protecting the floor beneath. It cost about $25.

    Green Onions - Beauty of stop

    I do enjoy messing around with the stop setting for color every now and then, though I will take @Mitch Towne's comment that it makes your technique sound more exposed as a reason I *like* playing with a Leslie... 😉 

     

    I only ever get to play with it on my clones, though; my real Hammond is hooked up to a 147 that only does chorale and tremolo, no brake. Well, except when one of the motors is acting up! My most frequent use of Stop is when I'm trying to get more of a combo organ sound, like if I'm covering The Doors or something. But the more Hammond I play, the more I'm trying to coax out more of the tonal palette from song to song, section to section.

     

    An EIS solid-state relay (now Trek) can give chorale-stop-tremolo by using a 3-postion hand switch or (I expect - ask Trek) a 2-position hand switch and an external switch for stop.

    On the sound of Zildian Ks

    in Hit It!

    Posted

    I'm a 71 y/o sax/keys player.  Throughout my years playing, drummers talked about Ks, though could never explain why.  I was happy to run across this (new to me) YT video of a drummer trying out a selection of Ks.  I sent the link to a longtime drummer/friend and told I thought maybe one had to hear them to know.  His response:

     

    Quote

    "Absolutely right Brad, one has to hear the cymbals to appreciate and their application, in this instance jazz playing. Notice how easy it is to get a “crash” effect with control over decay of the crash, then right back into keeping time. Also, the K’s have a great stick sound to them without building in volume."

     

    I wouldn't have thought 17 minutes of someone playing cymbals would hold my interest, but I was fascinated by it.

     

     

    What genre of music is your bane?

    For me, it's the genre that plays through the overheads in chain grocery stores, big box stores, and the like.  Except for their annoyance, unmemorable. They all sound the same. They have the same beat, with a forgettable melody sung by an autotuned female singing about nothing of interest with words I don't hear.
