Joyo JF-13, JF-14, JF-15 and JF-16 Amp Simulator Settings Worksheet available here

I have created a settings worksheet in PDF form, here:  joyoampsim_worksheet   that can help you remember favorite settings on your:jf13

  • Joyo JF-13 AC Tone
  • Joyo JF-14 American Sound
  • Joyo JF-15 California Sound
  • Joyo JF-16 British Sound    amplifier simulator pedals.  It’s configured to print 3 sets of settings per page on 8.5″ by 11″ paper, with the pedal names across the top (circle one), and space for sound “names” and descriptions.  Enjoy!

Korg I5M User Manual – Hard to find, but now you can find it here (too).


Korg I5M Interactive Music Module

The Korg I5M musical arrangement module is an amazing piece of music technology. I paid for mine what one might pay for a decent used rhythm module, so it was a fantastic deal.

However, it’s not very intuitive (yet) and I’d been searching for an online User Manual.  Several sites had the I5S manual – the one for the unit equipped with a keyboard, but I felt certain the I5M must have come with a manual of its own.

If you’re looking for the I5M User Manual, click here to download it from where I got it (with thanks).  Or, if the above link goes dead, try downloading it from my local copy of I5M manual and consider hosting it on your own site so it becomes easier to find.

Changing battery in Behringer Bass V-Amp

Changing the battery is very simple on the non-pro version of the Behringer Bass V-Amp (the one that looks like a guitar body, not the one that’s rack-mountable).

Preparation:  Unplug the unit – do not have any power going to this unit during this work, in case you drop the battery onto the circuit board when it’s under power – that could short things out and fry something important, after which you’ll be sad. Continue reading

Genz Benz El Diablo 60/60C Guitar Amp favourite tone settings template doc

I have created a 2-sided printable PDF template that allows one to mark and save favourite tone settings for the Genz Benz El Diablo 60-series tube guitar amps.   GenzBenz_Diablo60_SettingsTemplate

Print it out, then pencil in the dial settings you want for various “voicings”. Fill in or checkbox the appropriate arrow to indicate whether using the Warm or Hot channel, and lastly check the Pentode or Triode checkbox to indicate which mode one is running in.  Enjoy, hope this saves you some time. For me, I’m looking forward to really getting to know this amp.

Kaman KMD GV100S / GV100SD Circuit Diagram (PDF)

September 2013 I bought a Kaman KMD GV100S British-made hybrid tube guitar amp head (solid-state preamp stage, tube power amp stage, 100W RMS output), which I enjoyed very much for a period, but have since sold, having moved to a Genz Benz Diablo 60C combo amp, all tube/valve.

I was able to get a circuit diagram for the Kaman KD GV100S, which I’m sharing here:  Click KMD_GV100S to download this diagram in PDF format.  Enjoy!

On Augmented-Reality eyewear

Google is releasing information on, and asking for user ideas on a possible future product – augmented-reality eyewear (see this article: ).

I have little doubt this will come to pass in some form or another, and no doubt the glasses will eventually have both a microphone and speakers, making them a natural replacement for or extension of the hand-held telephone. Where the iPod and iPad are rapidly becoming the ubiquitous means by which people stay connected, and stay abreast of what’s happening in their lives, a technology like this will provide a means of accessing that information, and have that data intelligently provided to them based on a host of current behaviours and the user’s current location.

Read that article – this is likely coming sometime soon, and could possibly displace (or at least seriously supplement) things like iPhones and iPads… like how about a device like an iPhone you never have to look at – it’s just a store of data and auxiliary processing horsepower?  Maybe even that won’t be necessary if miniaturization continues at its current pace. 

I do think the term “Augmented Reality” is a bit self-important sounding, though, and I hope they come up with a new terminology for this before it dies just out of the rancour of those who rail at anything too radical, technically  (like shaved under-arms, elastic waistbands in underwear, and Q-Tips, for example).

On the down side, our no-texting-no-cellphone-while-driving laws will doubtless need to be expanded or seriously reworked.

I could see a device like this being the newest seriously-distracting element on our highways, and I could further envision people falling onto subway tracks in droves as they pay attention to what they see in their new eyewear instead of paying attention to where they are. 

It may be the final thing that proves that we’re no way near as good at multi-tasking as we believe ourselves to be. 

Hopefully it will be smart enough to know it’s in a moving car and will gracefully and smartly shut off its display (at the very least).

Ah, well… our planet is seriously over-populated… maybe lemmings have something like this built in (they don’t)… perhaps they’re just plugged into an augmented reality when their populations are too dense and they head for the sea?

Nikon F4s

I have finally acquired a pro-level Nikon film camera body – an F4s.  This past weekend yielded some better weather and lovely quality of sunlight, as I have been dying to go off into the hinterland to take some photos with this amazing instrument.  Many photo experts feel that this was the most innovative and game-changing camera that Nikon has produced, before or since, as most have been incremental changes over their predecessors.

For some great reviews and other resources on the Nikon F4, see:

Ken Rockwell’s review of the F4

Nikonian’s Review of the F4

Nikon's F4S - the most innovative Nikon ever?

Nikon’s F4s – probably the most innovative camera Nikon ever made

The F4s weighs a lot, and feels so very solid and competent in the hand.   I was recently able to get a Type E replacement focusing screen for it, which has faint grid lines overlaying the viewing field/focusing screen.  This will help a lot with my perpetual problem of getting the horizon just slightly askew (which can also be attributed to not taking enough time on the shot to know that I have all the variables just so), and will also aid in thinking through compositional elements better.  Realistically nobody needs grid lines to do these things if he can take his time, but sometimes the moment passes too quickly, so the shot must be taken regardless.

Basia and I went to lovely Niagara-on-the-Lake Monday afternoon, and I took a number of shots with the F4s while there – looking forward to getting those developed when I finish the roll.

Will scan and post some of the better shots into this article later.
