My tremolos are easily my favourite circuits, and have occupied more of my design time than anything else. This was my first unique effect circuit design from scratch, which I started in high school. Development took over a decade before I was happy with the way that it sounded and functioned.
By shining a fluctuating light against a photo-sensitive field, this tremolo uses all-analog photocoupling to restrict and modulate the output volume. Careful waveform construction, with non-linear shaping, creates an organic and lively volume fluttering, far divorced from sounding like a basic electronic waveform function. The square wave is similarly processed, so as not to sound like a computerised chop.
Symmetry switch: This toggles between two modes which are subtly different. The asymmetric mode (up) has a slightly uneven rhythmic pattern - think of the first spinning liquid can tremolos. I feel this mode is sweeter when the playing tempo is not matching with the tremolo rate.
The symmetrical mode (down) has an even 360 degree spin, with a very slightly deeper scoop. It has a classically pronounced tremolo shape - think of a rotary speaker.
I generally prefer to use the asymmetrical mode for the square wave, as the signal stays 'on' longer, with less gap time. The symmetrical mode (down) square wave will give more perceived depth.
This circuit operates with in a split rail power supply for increased headroom, and has a very low noise level.
As with all of my tremolo models, you should expected perceived unity volume with all depth and rate settings, without having to make any manual volume adjustments. The wet level can be adjusted internally by a trimpot.
Warranty & Returns
All New products are covered by the manufacturers new warranty. Please check their website for the length of warranty and warranty conditions. If an item you receive is faulty get in touch with us ASAP. Second Hand products come with a 4 week warranty from us. If there is an issue let us know ASAP! This covers normal use and does not cover accidental damage, misuse, wrong power plugged into it, modding, water damage or any other damage caused by mistreatment. Just treat it nice and all will be good!
Shipping
We send A LOT of packages every week so don't worry about the shipping side of things!
We've never lost a thing and your awesome new gear will be packed up really well to avoid any damage in transit.
If your order comes in before 2pm we will ship it same day. Most of the time we pack things up all the way to 4pm so just call if you need it to leave same day after 2pm.
We ship mainly with Australia Post but may use a courier depending on location and size of the package.
Free Post ships with Australia Post standard and expected shipping times are between 4-6 business days depending on location. It will be longer to outside of metro and rural areas.
Express Post will usually be with you next business day in metro areas of QLD, NSW, SA, VIC and TAS. WA will take 2 days to metro and extra days after that to out side metro and rural areas.
Everything we ship has a tracking number with the exception of some power cables and smaller envelope packages. You will be emailed tracking once your order has been shipped!
