    Change numbers, one for each pedal state: Bypass, Effect and Extended. With TS8-MS you have a quality tubescreamer guitar effect and a guitar amplifier channel switcher (with 2 independent relays), both functions being MIDI or Footswitch controlled. This pedal can sit not only under your foot, but also in a rack drawer.

  • Page 5: Settings

    Note: Because TS8-MS is not configured with a second external MIDI connector for MIDI Through function, you will have to place it last in your chain of MIDI devices that needs to be MIDI controlled.
  • Page 6 MIDI Channel for whatever function (trannsmit or receive) you need to use with TS8-MS in your rig. If you whant to control it with MIDI, then you will couple the MIDI jumper cable inside the pedal to the MIDI Receive socket (RX) on the circuit board;...
  • Page 7 To switch amplifier channels, you will need a dedicated cable from TS8-MS external switching connector to the amplifier's external switching connector. It may be a stereo-to-stereo cable or an Y- cable configured at one end with a stereo jack and at the other with two mono jacks.

  • Page 8: Setting External Switching Relays Pattern On Footswitch Action

    Setting External Switching Relays pattern on footswitch action You need to choose the desired External Switching Relay combination when overdrive is Off (Bypass) or On (Effect), and set the Multi Function switch on the circuit board inside accordingly. The state of these relays will decide what amplifier Channel is switched. For example, if Multi Function hex switch is set to position 2 it means that, in Bypass pedal state, the External Swithcing Relays are Off, only Relay 2 is On in Effect state and both relays are On in Extended Mode.
  • Page 9  power off pedal (battery or external power adapter),  set the Multi Function switch to position "A",  press down and hold the footswitch,  power on the pedal (from battery or external power adapter),  hold the footswitch for 3 more seconds, until the LED's are lit as indicated, ...

  • Page 10: Reset To Factory Defaults

    "On" or "Off" switching relay state execution, the same "100ms momentary ON" command is issued in this mode of switching, so, inevitably, the relay logic state in TS8-MS is always alternating on the next execution. As a consequence, it is up to the amp to acknoledge, interpret and respond to these external momentary commands.

  • Page 11: In Operation

    In Operation TS8-MS Controls 1. Momentary footswitch for Effect/Bypass/Extended switching, External Switching Relay action and MIDI transmit function 2. Audio Output Connector 3. Clipping Mode Selector 4. Gain Control (Logarithmic, Less/More Gain Mod) 5. MIDI Input/Output Connector 6. 1/4 TRS Connector for External Switching - 2 relays 7.

  • Page 12: Tone Control

    All LED's are used for visual indication while in Setup mode. Footswitch Action The footswitch used in TS8-MS is momentary (NO - normal open) type of switch, supporting both short and long pushes (during which time the switch contact is momentarely closed), each action type having different results.
  • Page 13 If you only need to switch between two amp's channels and don't need the Extended mode at all, simply don't push the footswitch longer than one second. Note: If you power off pedal and then power it on again, TS8-MS will remember last command/state before power off.

  • Page 14: Dc Power Supply

    DC Power Supply TS8-MS pedal can be powered using a 9 Volt alkaline battery or a 9 Volt DC Power Adapter with a barrel of 5.5 mm and a hole of 2.1 mm with minus polarity on the center Instrument cable jack must be inserted into the input connector for the circuit to power on, if battery is the power source.

    (ex. reverb, EQ stage, solo, boost, etc). In the picture bellow, TS8-MS Overdrive pedal is used to also switch amp's channels but you can use the switching relays in the pedal to switch an amp feature.

  • Page 16: Using An External Midi Controller To Control Ts8-Ms Analog Overdrive And Switch Amplifier's Channels

    So, you need to switch amp's Channel and engage the overdrive at the same time. TS8-MS does just that and you can do this with only one footswitch push! The External Switching Relays are completely isolated from pedal audio circuit.

  • Page 17: Receiving Program Change Midi Messages

    When you use Program Change to control TS8-MS it is advisable to use PC messages alone, without accompanying with conflicting Control Change (CC) messages. However, you may use both type of commands, at once, to control everything in your MIDI rig - they just need to be programed correctly.

  • Page 18: Receiving Control Change Midi Messages

    When working with Control Change commands CC 83, CC 84, CC 85 and CC 86 - which control more relays at once in TS8-MS -, you must program your MIDI Controller in such a way that when a preset (Program Change command) is transmitted, only one of these CC numbers will be transmitted.

  • Page 19: Using Ts8-Ms As Analog Overdrive, Amplifier Channel Switcher And Simple Midi Controller (Transmitter) On Footswitch Action

    Change message with all of the following CC numbers allocated, each controlling only one relay in TS8-MS: CC 80 - Bypass Relay, CC 81 - External Switching Relay 1, CC 82 - External Switching Relay 2. This way you can control these relays within one Program Change preset, even after the preset is transmitted to your other MIDI devices, using dedicated on/off physical buttons.

  • Page 20: Ts8-Ms Customizations

     PC# 3 when pedal is in Extended mode. With TS8-MS as "MIDI Controller", you can cycle through three MIDI presets on your other MIDI devices and switch amplifier channels at the same time. Of course, to do so, you also need to connect the External Switching Relays to the amp's external switching connector using either a stereo or an "Y"...

  • Page 21: Change Indication Led's Color

    Red LED's - clipping around 1.6V, for a wilder distortion in higher gain setting or an Almost Clean boost in lower gain setting. Note: If you aim for the smoothest clipping, we recommend you try some 1N34 Germanium diodes which nicely complement single coil pickups. However, they might sound "too compressed" with humbucker pickups.

    Not responding to MIDI commands - Set MIDI Channel to the same one used by transmitting controller. Restart pedal. Restore to factory defaults. Not sending MIDI commands - Verify pedal MIDI Channel to be the same as the one used by the receiving device.
